OneDrive
Microsoft OneDrive (formerly SkyDrive) is a file hosting service operated by Microsoft. First launched in August 2007, it enables registered users to share and synchronize their files. OneDrive also works as the storage backend of the web version of Microsoft Office. OneDrive offers 5 GB of storage space free of charge, with 100 GB, 1 TB, and 6 TB storage options available either separately or with Office 365 subscriptions. The OneDrive client app adds file synchronization and cloud backup features to its device. The app comes bundled with Microsoft Windows and is available for macOS, Android, iOS, Windows Phone , Xbox 360, Xbox One, and Xbox Series X and S. In addition, Microsoft Office apps directly integrate with OneDrive. History. At its launch the service, known as "Windows Live Folders" at the time (with a codename of "SkyDrive"), was provided as a limited beta available to a few testers in the United States. On August 1, 2007, the service was expanded to a wider audience. Shortly thereafter, on August 9, 2007, the service was renamed Windows Live SkyDrive and made available to testers in the United Kingdom and India. SkyDrive was initially available in 38 countries and regions, later expanded  to 62. On December 2, 2008, the capacity of an individual SkyDrive account was upgraded from 5 GB to 25 GB, and Microsoft added a separate entry point called "Windows Live Photos" which allowed users to access their photos and videos stored on SkyDrive. This entry point allowed users to add "People tags" to their photos, download photos into Windows Photo Gallery or as a ZIP file, as well as viewing Exif metadata such as camera information for the photos uploaded. Microsoft also added the ability to have full-screen slide shows for photos using Silverlight. SkyDrive was updated to  Wave 4 release on June 7, 2010, and added the ability to work with Office Web Apps (now known as Office Online), with versioning. In this update, due to the discontinuation of Windows Live Toolbar, the ability to synchronise and share bookmarked web links between users via SkyDrive was also discontinued. However, users were still able to use Windows Live Mesh, which replaced the previous Windows Live Favorites, to synchronize their favorites between computers until its discontinuation in February 2013. In June 2010, users of Office Live Workspace, released in October 2007, were migrated to "Windows Live Office". The migration  included all existing workspaces, documents, and sharing permissions. The merger of the two services was a result of Microsoft's decision to merge its Office Live team into Windows Live in January 2009, as well as several deficiencies with Office Live Workspace, which lacked high-fidelity document viewing and did not allow files to be edited from within the web browser. Office Live Workspace also did not offer offline collaboration and co-authoring functionality – instead documents were "checked out" and "checked in", though the service did integrate with SharedView for real-time screen sharing. On June 20, 2011, Microsoft overhauled  the user interface for SkyDrive, built using HTML5 technologies. The updated version featured caching, hardware acceleration, HTML5 video, quick views, cleaner arrangement of photos and infinite scrolling. Microsoft also doubled the file size limit from 50 MB to 100 MB per file. With this update, Microsoft consolidated the different entry points for SkyDrive, such as "Windows Live Photos" and "Windows Live Office", into one single interface. Files and folders shared with a user, including those in Windows Live Groups, were also accessible in the new interface. On November 29, 2011, Microsoft updated SkyDrive to make sharing and file management easier , as well as HTML5 and other updates. This update also allowed users to see how much storage they had (and how much they had used), a feature that had been removed in the previous update as part of the redesign. On December 3, 2011, Microsoft released SkyDrive apps for iOS and Windows Phone, which are available in the App Store and Windows Phone Store respectively. On April 22, 2012, Microsoft released a SkyDrive desktop app for Windows Vista, 7 and 8, as well as macOS, allowing users to synchronize files on SkyDrive, much like Windows Live Mesh, and to "fetch  files on their computer via the web browser. In addition, SkyDrive also provided additional storage available for purchase and reduced the free storage space for new users to 7 GB (from 25 GB.) Existing users were offered a free upgrade offer to retain their 25 GB of free storage. The updated SkyDrive also allowed files up to 2 GB in size (uploaded via the SkyDrive desktop app). The update also brought additional features such as Open Document Format (ODF) capability, URL shortening services and direct sharing of files to Twitter. On August 14, 2012, Microsoft announced a new update for 	OneDrive
