c:/ System Volume information.... what is this?

These are the files created by the System Restore function.  They are deleted by disabling System Restore.

Press the Windows Key+Break
Click on the System Restore tag
Check the "Turn off System Restore On All Drives" box
Click Apply
Click OK.

All system Restore files will have been deleted.

To enable System Restore repeat the above but this time Uncheck the box.

Good luck
