Folder redirection

In computing, and specifically in the context of Microsoft Windows operating systems, Microsoft refers to Folder Redirection when automatically re-routing I/O to/from standard folders (directories) to use storage elsewhere on a network.

It is often used in an office network environment, to ensure that users do not store data locally, when a network device is the preferred storage location. Folder Redirection allows saving data regardless of storage location and separates user data from profile data decreasing the time required to log on. Other advantages include [ [http://technet2.microsoft.com/windowsserver/en/library/60b2157c-aa5b-44f2-b045-b74d2fd1bf701033.mspx?mfr=true Folder Redirection Overview] ] :
* Data is stored on a server where it can be backed up
* If the same redirection is applied to multiple users, all data is stored in the one location
* Allows for sharing of data between users
* Allows system administrators to spend less on workstation hard drives, and more on file server hard drives

Under Microsoft Windows, the redirection is often performed by Group Policy [ [http://support.microsoft.com/kb/274443/ How to dynamically create security-enhanced redirected folders by using folder redirection in Windows] ] , when used in an Active Directory environment. It can also be performed by manually editing the Windows Registry, or with tools such as Tweak UI. Disk quotas can be used to limit the amount of space taken up by users' special folders. The %username% and %userprofile% environment variables can also be used with Folder Redirection.

Up to Windows XP, the "Application Data", "Desktop", "My Documents", "My Pictures", and "Start Menu" folders can be redirected to a file server. Windows Vista introduces the ability to independently redirect up to 10 user profile sub-folders to a network location.

The equivalent functionality is achieved in Unix-like systems by using mount or ln and a NFS.
