On every Windows compatible computer hard drive even external USB drives you find a “System Volume Information” folder. You’ll only see it if you have Windows set to show hidden files and folders, but it’s always there. So many have seen it but have been wondering what is it for?
So you could have tried to open this folder and failed, this is because drives formatted with the NTFS file system , this folder’s permissions are set to prevent everyone from accessing the folder, even users with Administrator permissions. Double-click the folder and you’ll see an error message saying the “location is not available” and “access is denied.”

This is normal, because Windows uses this folder for certain system-level features. The permissions are set to prevent users and programs without the appropriate permissions from tampering with the files inside and interfering with important system functions.
Windows stores System Restore Points in the System Volume Information folder.If you need to shrink the size of the System Volume Information folder, you can do so from the Control Panel. Head to Control Panel > System and Security > System > System Protection. Under Protection Settings, you can choose whether System Restore is enabled and control how much disk space Windows uses for System Restore points.
For example, the System Volume Information folder also contains information used by the content indexing service databases that speed up your file searches, the Volume Shadow Copy service for backups, and the Distributed Link Tracking Service databases used to repair shortcuts and links.
If you have a drive formatted with the exFAT or FAT32 file systems an external USB drive, for example you can open the System Volume Information folder and look inside.
For example, on one of our USB drives, we saw two files inside: IndexerVolumeGuid and WPSettings.dat.
The IndexerVolumeGuid file assigns a unique identifier to this drive. The Windows indexing service examines the files on the drive and indexes them. When you connect the drive to the computer in the future, Windows checks the identifier and knows which search database to associate with the drive.
You can then use Windows search fetaures, such as the search box in the Start menu, Cortana on Windows 10 or the search box in the File Explorer or Windows Explorer, to quickly search for files on the drive.
You shouldn’t delete the System Volume Information folder. On NTFS-formatted drives, Windows won’t normally let you access this folder, much less delete it. On exFAT or FAT32-formatted drives, you can choose to delete the folder—but Windows will just recreate it in the future, since it needs it.
Windows stores important system data here, and you should leave the folder alone. Don’t attempt to change the permissions on the folder to delete it.
If the System Volume Information folder is using a lot of space, reduce the space allocated to System Restore in Windows. If seeing the folder bothers you, just set Windows to hide hidden files and folders.
