On every Windows drive—even external USB drives—you’ll find a “System Volume Information” folder. You’ll only see it if you have Windows set lớn show hidden files và folders, but it’s always there. So what is it for?


Why Can’t I Open the Folder?

RELATED: What"s the Difference Between FAT32, exFAT, & NTFS?

On drives formatted with the NTFS tệp tin system, this folder’s permissions are set to prevent everyone from accessing the folder, even users with Administrator permissions. Double-click the thư mục and you’ll see an error message saying the “location is not available” và “access is denied.” This is normal.

That’s because Windows uses this thư mục for certain system-level features. The permissions are set to lớn prevent users—and programs without the appropriate permissions—from tampering with the files inside and interfering with important system functions.

What Is It For?

RELATED: How lớn Use System Restore in Windows 7, 8, & 10

Among other things, Windows stores System Restore points in the System Volume Information folder.

If you need khổng lồ shrink the size of the System Volume Information folder, you can vì so from the Control Panel. Head to Control Panel > System & Security > System > System Protection.

Just disabling System Protection for a drive won’t actually delete the System Volume Information folder. Windows stores more than just restore points here.

If you have a drive formatted with the exFAT or FAT32 tệp tin systems—an external USB drive, for example—you can xuất hiện the System Volume Information folder and look inside.

For example, on one of our USB drives, we saw two files inside: IndexerVolumeGuid và WPSettings.dat.

RELATED: How lớn Choose Which Files Windows search Indexes on Your PC

The IndexerVolumeGuid tệp tin assigns a chất lượng 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 tìm kiếm database lớn associate with the drive. You can then use Windows tìm kiếm features, such as the search box in the Start menu, Cortana on Windows 10, or the tìm kiếm box in the file Explorer or Windows Explorer, lớn quickly search for files on the drive.

WPSettings.dat is another file created by a Windows service, but we’re not sure exactly what it’s for. There’s no official documentation on this file.

Can I Delete the Folder?

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 lớn delete the folder—but Windows will just recreate it in the future, since it needs it.

Windows stores important system data here, & you should leave the thư mục alone. Don’t attempt khổng lồ change the permissions on the thư mục to delete it.

If the System Volume Information folder is using a lot of space, reduce the space allocated khổng lồ System Restore in Windows. If seeing the thư mục bothers you, just set Windows to lớn hide hidden files và folders.
