From Windows 2000 onwards a folder called 'System Volume Information' resides in the root of the Windows inatallation partition, usually C:\\ . The directory security is set so that not even Administrators can access it, although this can be changed. Files in thie folder if changed/deleted could cause certain functions to fail.
- System Restore points: All beginning with "_restore" .
- Distributed Link Tracking Service databases: This service tries to repair broken shortcuts.
- File Indexes: Databases for the native file indexer.
- Volume Snapshot Service databases: Used to allow volume shadowing - this allows previous versions of files to be restored on the same hard drive allowing restores to be done by users so long as it is not deleted.
- WinFS databases: Longhorn only
