Google Drive is a file storage and synchronization service developed by Google. Launched on April 24, 2012, Google Drive allows users to store files in the cloud, synchronize files across devices, and share files. In addition to a website, Google Drive offers apps with offline capabilities for Windows and macOS computers, and Android and iOS smartphones and tablets. Google Drive encompasses Google Docs, Sheets and Slides, an office suite that permits collaborative editing of documents, spreadsheets, presentations, drawings, forms, and more. Files created and edited through the office suite are saved in Google Drive.
Google Drive offers users 15 gigabytes of free storage, with 100 gigabytes, 1 terabyte, 2 terabytes, 10 terabytes, 20 terabytes, and 30 terabytes offered through optional paid plans. Files uploaded can be up to 5 terabytes in size. Users can change privacy settings for individual files and folders, including enabling sharing with other users or making content public. On the website, users can search for an image by describing its visuals, and use natural language to find specific files, such as "find my budget spreadsheet from last December".
The website and Android app offer a Backups section to see what Android devices have data backed up to the service, and a completely overhauled computer app released in July 2017 allows for backing up specific folders on the user's computer. A Quick Access feature can intelligently predict the files users need.
Google Drive is a key component of G Suite, Google's monthly subscription offering for businesses and organizations. As part of select G Suite plans, Drive offers unlimited storage, advanced file audit reporting, enhanced administration controls, and greater collaboration tools for teams.
Following the launch of the service, Google Drive privacy policy was heavily criticized by some members of the media. Google has one set of Terms of Service and Privacy Policy agreements that cover all of its services, meaning that the language in the agreements grants the company broad rights to reproduce, use, and create derivative works from content stored on Google Drive. While the policies also confirm that users retain intellectual property rights, privacy advocates raised concerns that the licenses grant Google the rights to use the information and data to customize advertising and other services Google provides. In contrast, other members of the media noted that the agreements were no worse than those of competing cloud storage services, but that the competition uses "more artful language" in the agreements, and also stated that Google needs the rights in order to "move files around on its servers, cache your data, or make image thumbnails".
As of March 2017, Google Drive has 800 million active users, and as of September 2015, it has over one million organizational paying users. As of May 2017, there are over two trillion files stored on the service.

Platforms
Google Drive was introduced on April 24, 2012 with apps available for Windows, macOS, and Android, as well as a website interface, with an iOS app under development. The iOS app was released in June 2012.
Computer apps
Google Drive is available for PCs running Windows 7 or later, and Macs running OS X Lion or later.
Google indicated in April 2012 that work on Linux software was underway, but there was no news on this as of November 2013.
In April 2012, Google's then-Senior Vice President Sundar Pichai said that Google Drive would be tightly integrated with Chrome OS version 20.
In October 2016, Google announced that, going forward, it will drop support for versions of the computer software older than 1 year.
In June 2017, Google announced that a new app called Backup and Sync would replace the existing separate Google Drive and Google Photos desktop apps, creating one unified app on desktop platforms. Originally intended for release on June 28, its release was delayed until July 12.
In September 2017, Google announced that it will discontinue the Google Drive desktop app in March 2018 and end support in December 2017.
Mobile apps
Google Drive is available for Android smartphones and tablets running Android 4.1 "Jelly Bean" or later, and iPhones and iPads running iOS 8 or later.
In August 2016, Google Drive ended support for Android devices running Android 4.0 "Ice Cream Sandwich" or older versions, citing Google's mobile app update policy, which states: "For Android devices, we provide updates for the current and 2 previous Android versions." According to the policy, the app will continue to work for devices running older Android versions, but any app updates are provided on a best-efforts basis. The policy also states a notice will be given for any planned end of service.
Website interface
Google Drive has a website that allows users to see their files from any Internet-connected computer, without the need to download an app.
The website received a visual overhaul in 2014 that gave it a completely new look and improved performance. It also simplified some of the most common tasks, such as clicking only once on a file to see recent activity or share the file, and added drag-and-drop functionality, where users can simply drag selected files to folders, for improved organization.
A new update in August 2016 changed several visual elements of the website; the logo was updated, search box design was refreshed, and the primary color was changed from red to blue. It also improved the functionality to download files locally from the website; users can now compress and download large Drive items into multiple 2 GB .zip files with an improved naming structure, better Google Forms handling, and empty folders will now be included in the .zip, thereby preserving the user's folder hierarchy.

Storage
Individual user account storage
Google gives every user 15 GB of free Drive storage space, which is shared across files in Google Drive, messages and attachments in Gmail, and pictures and videos in Google Photos. Google Docs, Sheets and Slides files do not count towards the storage limit. An unlimited number of photos at maximum 16 megapixels and videos at maximum 1080p resolutions are stored for free using the "High quality" setting in Google Photos. Using the "Original quality" setting uses Google Drive quota.
Users can purchase additional space through either a monthly or yearly payment. The option of yearly payments was introduced in December 2016, and is limited to the 100 GB or 1 TB storage plans. Furthermore, the yearly payments offer a discount.
As of 2017, these are the storage plans offered by Google:
Storage purchases renew automatically at the end of the subscription period. Users can upgrade their storage plan anytime, with the new storage tier taking effect immediately. If the auto-renewal fails, a 7-day grace period is offered for users to update their payment information. When the storage subscription expires or is cancelled, storage limit is set back to the 15 GB free level at the end of the subscription period. Users can still access all their content, but will not be able to add anything beyond the storage limit, which means:
- Users cannot add new files to Google Drive, with the exception of Google Docs, Sheets, or Slides files, which do not take up space. Synchronization between Drive and the local device will stop.
- Users with the "Original quality" setting in Google Photos cannot upload new photos or videos.
- Any incoming emails in Gmail will be returned to the sender.
Varying levels of free additional storage are offered on the purchase of specific Android devices from Motorola and HTC, and for various devices from Kensington, Asus, LG, and Panasonic.
G Suite storage
Google offers 30 GB of Drive storage for all G Suite Basic customers, and unlimited storage for those using G Suite Business or G Suite for Education, as long as there are at least 5 members. Associations with less than 5 members get 1 TB per user.
Storage scheme revisions
Before the introduction of Google Drive, Google Docs initially provided 15 GB of storage free of charge. On April 24, 2012, Google Drive was introduced with free storage of 5 GB. Storage plans were revised, with 25GB costing $2.49/month, 100GB costing $4.99/month and 1TB costing $49.99/month.
Originally, Gmail, Google Docs and Picasa had separate allowances for free storage and a shared allowance for purchased storage. Between April 2012 and May 2013, Google Drive and Google+ Photos had a shared allowance for both free and purchased storage, whereas Gmail had a separate 10 GB storage limit, which increased to 25 GB on the purchase of any storage plan.
In September 2012, Google announced that a paid plan would now cover total storage, rather than the paid allocation being added to the free; e.g. a 100 GB plan allowed a total of 100 GB rather than 115 GB as previously.
In May 2013, Google announced the overall merge of storage across Gmail, Google Drive and Google+ Photos, allowing users 15 GB of unified free storage between the services.
In March 2014, the storage plans were revised again and prices were reduced by 80% to $1.99/month for 100 GB, $9.99/month for 1TB, and $99.99/month for 10 TB. This was much cheaper than competitors Dropbox and OneDrive offered at the time. The 25 GB and 200 GB plans were discontinued and the 2 TB, 4 TB, 8 TB and 16 TB plans were replaced with 10 TB, 20 TB and 30 TB. Users were automatically upgraded to the new pricing scheme.
In most cases during these changes, users could continue with their existing plans as long as they kept their accounts active and did not make any adjustments to the plan. However, if the account lapsed for any reason, users had to choose from current plans.
Features
Sharing
Google Drive incorporates a system of file sharing in which the creator of a file or folder is, by default, its owner. The owner can regulate the public visibility of the file or folder. Ownership is transferable. Files or folders can be shared privately with particular users having a Google account, using their @gmail.com email addresses. Sharing files with users not having a Google account requires making them accessible to "anybody with the link". This generates a secret URL for the file, which may be shared via email or private messages. Files and folders can also be made "public on the web", which means that they can be indexed by search engines and thus can be found and accessed by anyone. The owner may also set an access level for regulating permissions. The three access levels offered are "can edit", "can comment" and "can view". Users with editing access can invite others to edit.
Third-party apps
A number of external web applications that work with Google Drive are available from the Chrome Web Store. To add an app, users are required to sign into the Chrome Web Store, but the apps are compatible with all supported web browsers. Some of these apps are first-party, such as Google Docs, Sheets and Slides. Drive apps operate on the online files, and can be used to view, edit and create files in various formats, edit images and videos, fax and sign documents, manage projects, create flowcharts, etc. Drive apps can also be made the default for handling file formats supported by them. Some of these apps also work offline on Google Chrome and Chrome OS.
All of the third-party apps are free to install. However, some have fees associated with continued usage or access to additional features. Saving data from a third-party app to Google Drive requires authorization the first time.
The Google Drive software development kit (SDK) works together with the Google Drive user interface and the Chrome Web Store to create an ecosystem of apps that can be installed into Google Drive. In February 2013, the "Create" menu in Google Drive was revamped to include third-party apps, thus effectively granting them the same status as Google's own apps.
In March 2013, Google released an API for Google Drive that enables third-party developers to build collaborative apps that support real-time editing.
File viewing
The Google Drive viewer on the web allows the following file formats to be viewed:
- Native formats (Docs, Sheets, Slides, Forms, Drawings)
- Image files (.JPEG, .PNG, .GIF, .TIFF, .BMP, .WEBP)
- Video files (.WEBM, .MPEG4, .3GPP, .MOV, .AVI, .MPEG, .MPEGPS, .WMV, .FLV, .OGG)
- Audio formats (.MP3, .M4A, .WAV, .OGG)

- Adobe Illustrator (.AI)
- Adobe Photoshop (.PSD)
- Autodesk AutoCad (.DXF)
- Scalable Vector Graphics (.SVG)
- PostScript (.EPS, .PS)
- Fonts (.TTF)
- XML Paper Specification (.XPS)
- Archive file types (.ZIP, .RAR, tar, gzip)
- .MTS files
- Raw Image formats
Files in other formats can also be handled through third-party apps that work with Google Drive, available from the Chrome Web Store.
File limits
Files uploaded, but not converted to Google Docs, Sheets, or Slides formats, may be up to 5 TB in size. There are also limits, specific to file type, listed below:
Quick Access
Introduced in the Android app in September 2016, Quick Access uses machine learning to "intelligently predict the files you need before you've even typed anything". The feature was announced to be expanded to iOS and the web in March 2017, though the website interface received the feature in May.
Search
Search results can be narrowed by file type, ownership, visibility, and the open-with app. Users can search for images by describing or naming what is in them. For example, a search for "mountain" returns all the photos of mountains, as well as any text documents about mountains. Text in images and PDFs can be extracted using optical character recognition. In September 2016, Google added "natural language processing" for searching on the Google Drive website, enabling specific user search queries like "find my budget spreadsheet from last December". In February 2017, Google integrated Drive and the Google Search app on Android, letting users search for keywords, switch to an "In Apps" tab, and see any relevant Drive files.
Backups
In December 2016, Google updated the Android app and website with a "Backups" section, listing the Android device and app backups saved to Drive. The section lets users see what backups are stored, the backups' sizes and details, and delete backups.
In June 2017, Google announced that a new app, "Backup and Sync", would be able to synchronize any folder on the user's computer to Google. The app was released on July 12, 2017.
Metadata
A Description field is available for both files and folders that users can use to add relevant metadata. Content within the Description field is also indexed by Google Drive and searchable.
Accessibility to the visually impaired
In June 2014, Google announced a number of updates to Google Drive, which included making the service more accessible to visually impaired users. This included improved keyboard accessibility, support for zooming and high contrast mode, and better compatibility with screen readers.
Save to Google Drive browser extension
Google offers an extension for Google Chrome, Save to Google Drive, that allows users to save web content to Google Drive through a browser action or through the context menu. While documents and images can be saved directly, webpages can be saved in the form of a screenshot (as an image of the visible part of the page or the entire page), or as a raw HTML, MHTML, or Google Docs file. Users need to be signed into Chrome to use the extension.
Mobile apps
The main Google Drive mobile app supported editing of documents and spreadsheets until April 2014, when the capability was moved to separate, standalone apps for Google Docs, Sheets, and Slides. The Google Drive app on Android allows users to take a photo of a document, sign, or other text and use optical character recognition to convert to text that can be edited. In October 2014, the Android app was updated with a Material Design user interface, improved search, the ability to add a custom message while sharing a file, and a new PDF viewer.
Encryption
Before 2013, Google did not encrypt data stored on its servers. Following information that the United States' National Security Agency had "direct access" to servers owned by multiple technology companies, including Google, the company began testing encrypting data in July, and enabled encryption for data in transit between its data centers in November. However, as of 2015, Google Drive does not provide client-side encryption.
Professional editions
Google Drive for Work
Google Drive for Work is a business version, a part of G Suite (formerly Google Apps for Work), announced at the Google I/O conference on June 25, 2014 and made available immediately. The service features unlimited storage, advanced file audit reporting and eDiscovery services, along with enhanced administration control and new APIs specifically useful to businesses. Users can upload files as large as 5 TB. A press release posted on Google's Official Enterprise Blog assured businesses that Google will encrypt data stored on its servers, as well as information being transmitted to or from them. Google will deliver 24/7 phone support to business users and has guaranteed 99.9% uptime for its servers.
In September 2015, Google announced that Google Drive for Work would be compliant with the new ISO/IEC 27018:2014 security and privacy standard, which confirmed that Google would not use data in Drive for Work accounts for advertising, enabled additional tools for handling and exporting data, more transparency about data storage, and protection from third-party data requests.
In March 2017, Google introduced Drive File Stream, making it possible for G Suite customers on Windows and macOS computers to search their Drive folders and download specific files on-demand rather than downloading all files during installation, potentially preventing large amounts of data from "gobbling up your hard drive". Additionally, the feature will guess what files users need in the future and download those files as well.
Google Drive for Education
Google Drive for Education was announced on September 30, 2014. It was made available for free to all Google Apps for Education users. It includes unlimited storage and support for individual files up to 5TB in size, in addition to full encryption.
Team Drives
In September 2016, Google announced Team Drives, a new way for teams to collaborate. Sharing and file ownership are managed for the entire team rather than one individual, and new users instantly get access to all files and information. In November, Google opened an Early Adopter Program, allowing G Suite Business and G Suite for Education customers to sign up, although Google noted that some functionality isn't yet supported by Team Drives.
Docs, Sheets and Slides
Google Docs, Google Sheets and Google Slides constitute a free, web-based office suite offered by Google and integrated with Google Drive. It allows users to create and edit documents, spreadsheets, and presentations online while collaborating in real-time with other users. The three apps are available as web applications, as Chrome apps that work offline, and as mobile apps for Android and iOS. The apps are compatible with Microsoft Office file formats. The suite also consists of Google Forms, Google Drawings and Google Tables (beta). While Forms and Tables are only available as web applications, Drawings is also available as a Chrome app. The suite is tightly integrated with Google Drive, and all files created with the apps are by default saved to Google Drive.
Reception
Features
In a review of Google Drive after its launch in April 2012, Dan Grabham of TechRadar wrote that the integration of Google Docs into Google Drive was "a bit confusing", mainly due to the differences in the user interfaces (UI) between the two, where Drive offers a "My Drive" section with a specific "Shared with me" view for shared documents. He stated that "We think the user interface needs a lot more work. It's like a retread of Google Docs at the moment and Google surely needs to do work here". He considered uploading files "fairly easy", but noted that folder upload was only supported through the Google Chrome web browser. The lack of native editing of Microsoft Office documents was "annoying". Regarding Google Drive's computer apps, he stated that the option in Settings to synchronize only specific folders was "powerful". He wrote that Drive was "a great addition to Google armoury of apps and everything does work seamlessly", while again criticizing the interface for being "confusing" and that the file view was "not quite intuitive enough" without file icons. Grabham also reviewed the mobile Android app, writing that "it's a pretty simple app that enables you to access your files on the move and save some for offline access should you wish", and praised Google Docs creation and photo uploading for being "easy". He also praised that "everything is easily searchable".
A review by Michael Muchmore of PC Magazine in February 2016 praised the service as "truly impressive" in creating and editing files, describing its features as "leading" in office-suite collaboration. He added that "Compatibility is rarely an issue", with importing and exporting options, and that the free storage of 15 gigabytes was "generous". However, he also criticized the user interface for being confusing to navigate, and wrote that "Offline editing isn't simple".
Ownership and licensing
Immediately after its announcement in April 2012, Google faced criticism over Google Drive privacy. In particular, privacy advocates have noted that Google has one unified set of Terms of Service and Privacy Policy agreements for all its products and services. In a CNET report, Zack Whittaker noted that "the terms and service have come under heavy fire by the wider community for how it handles users' copyright and intellectual property rights". In a comparison of Terms of Service agreements between Google Drive and competing cloud storage services Dropbox and OneDrive, he cited a paragraph stating that Google has broad rights to reproduce, use, and create derivative works from content stored on Google Drive, via a license from its users. Although the user retains intellectual property rights, the user licenses Google to extract and parse uploaded content to customize advertising and other services that Google provides to the user, and to promote the service. Summarized, he wrote that "According to its terms, Google does not own user-uploaded files to Google Drive, but the company can do whatever it likes with them". In a highly critical editorial of the service, Ed Bott of ZDNet wrote that language in the agreements contained "exact same words" as Dropbox used in a July 2011 Privacy Policy update that sparked criticism and forced Dropbox to update its policy once again with clarifying language, adding that "It's a perfect example of Google's inability to pay even the slightest bit of attention to anything that happens outside the Googleplex". Matt Peckham of Time criticized the lack of unique service agreements for Drive, writing that "If any Google service warrants privacy firewalling, it's Google Drive. This isn't YouTube or Calendar or even Gmail----the potential for someone's most sensitive data to be snooped, whether to glean info for marketing or otherwise, is too high. [...] Google ought to create a privacy exception that "narrows the scope" of its service terms for Google Drive, one that minimally states the company will never circulate the information generated from searching within [sic] your G-Drive data in any way."
In contrast, a report by Nilay Patel of The Verge stated that "all web services should be subject to harsh scrutiny of their privacy policies--but a close and careful reading reveals that Google's terms are pretty much the same as anyone else's, and slightly better in some cases", pointing to the fact that Google "couldn't move files around on its servers, cache your data, or make image thumbnails" without proper rights. In comparing the policies with competing services, Patel wrote that "it's clear that they need the exact same permissions--they just use slightly more artful language to communicate them".
Growth
On November 12, 2013, Google announced that Google Drive had 120 million active users, a figure that the company was releasing for the first time.
On June 25, 2014 at the Google I/O developer conference, Sundar Pichai announced that Google Drive now had 190 million monthly active users, and that it was being used by 58% of the Fortune 500 companies as well as by 72 of the top universities.
On October 1, 2014, at its Atmosphere Live event, it was announced that Google Drive had 240 million monthly active users. The Next Web noted that this meant an increase of 50 million users in just one quarter.
On September 21, 2015, it was announced that Google Drive had over one million organizational paying users.
In March 2017, Google announced that Google Drive had 800 million active users.
In May 2017, a Google executive stated at a company event that there were over two trillion files stored on Google Drive.
Downtime issues
Although Google has a 99.9% uptime guarantee for Google Drive for G Suite customers, Google Drive has suffered downtimes for both consumers and business users. During significant downtimes, Google's App Status Dashboard gets updated with the current status of each service Google offers, along with details on restoration progress. Notable downtimes occurred in March 2013, October 2014, and January 2016.
When the January 2016 outage was resolved, a Google spokesperson told The Next Web:
At Google we recognize that failures are statistically inevitable, and we strive to insulate our users from the effects of failures. As that did not happen in this instance, we apologize to everyone who was inconvenienced by this event. Our engineers are conducting a post-mortem investigation to determine how to make our services more resilient to unplanned network failures, and we will do our utmost to continue to make Google service outages notable for their rarity.
In an outage that affected all of Google's services for 5 minutes in August 2013, CNET reported that global Internet traffic dropped 40%.
