The System Volume Information Folder
The System Volume Information folder is a hidden folder in the root of
your C drive that the Windows System Restore tool uses to store its
information and restore points. It’s not just System Restore data that
gets stored in here though and the Windows Indexing Service uses it to
store search databases, the Volume Shadow Copy Service creates live
system backup data and also Distributed Link Tracking stores database
information to repair shortcuts and linked documents. Check Disk logs
are also saved here.

Deleting System Volume Information or its Files
Once you have gained ownership of the System Volume Information
folder, it’s then possible to access and delete any of the files
inside or the whole folder itself. We highly recommend you DO NOT do
this for the System Volume Information folder on your Windows drive
(C:). As we said earlier, it contains data for many other system
components besides System Restore and could make Windows unstable or
even crash. Besides, if you delete it from C, the whole folder will
simply be created again automatically.
