"This application automatically maintains older versions of files that are changed. When enabled, a hidden versions folder is provisioned in every user’s directory and is used to store old file versions. A user can revert to an older version through the web interface at any time, with the replaced file becoming a version. The app automatically manages the versions folder to ensure the user doesn’t run out of Quota because of versions.\n\t\tIn addition to the expiry of versions, the versions app makes certain never to use more than 50% of the user’s currently available free space. If stored versions exceed this limit, the app will delete the oldest versions first until it meets this limit. More information is available in the Versions documentation.":"此应用自动维护已修改的文件的旧版本。当启用时，应用会在每个用户的文件夹下生成一个隐藏的版本文件夹，以用于保存旧的文件版本。用户可以随时在web界面上回滚到旧版本，被替换的现有文件也将成为一个版本。此应用会自动管理版本文件夹以保证用户不会因版本导致把配额用完。\n\t\t除了版本过期，版本应用还将确保文件版本的使用容量不会超过现有可用空闲容量的50%。如果保存的版本超过这一限制，此应用将首先删除最旧的版本直到满足限制。更多信息请参考版本文档。",
