About System Volume Info :
The folder contains information that casual interference could cause problems with proper system functioning. Here are some of the things kept in that folder. (This list is not comprehensive.)
- System Restore points. You can disable System Restore from the "System" control panel.
- Distributed Link Tracking Service databases for repairing your shortcuts and linked documents.
- Content Indexing Service databases for fast file searches. This is also the source of the cidaemon.exe process: That is the content indexer itself, busy scanning your files and building its database so you can search for them quickly. (If you created a lot of data in a short time, the content indexer service gets all excited trying to index it.). Cidaemon might be Search Indexer in windows 7.
- Information used by the Volume Snapshot Service (also known as "Volume Shadow Copy") so you can back up files on a live system.
