System Reserved at 99.9%

Question

Windows 7 Professional 64bit

I have the following files in “System Volume Information”.  I can no longer even see them.  I have tried setting Owner to Administrator using Properties and “takeown,CACLS” commands.

I am at 99.9% of the space allocated to “System Reserved” which I believe is on a 3rd harddrive, although it does show alongside my SSD C: in the Disk Management view. I looked in the Register and the first id is not there.  The second is in VSS Default Provider in HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\BackupRestore\FilesNotToBackup.

-> You should leave this partition alone. It is used by the boot process and it does not matter if it is full.

-> You don't. Do you actually have a problem?

I keep getting the message from AVAST that the System Reserved is full.

Answer 2

System Volume Information folder contains critical data that helps Windows work. Hence, whatever you do, you can't access System Volume Information folder.

Further, the properties of the folder doesn't show the size, so if you can see the size in the folder's Properties dialog, then you must have access to the folder.

System Reserved is a partition where Windows boot information is present. It's recommended to hide the partition from Computer view by removing the drive letter. Refer the link to hide partitions/drives:

VSS means Volume Shadow Copy Service. It deals with performing copy and backup of files, which is utilized by services like System Restore and backup. The following link will be helpful:

Hence, if you're trying to delete any of the files you mentioned, System Restore or similar applications will not work properly and that you may not be able to restore the computer to a working state in case of any issue.

Answer 3

I keep getting the message from AVAST that the System Reserved is full.

This is because AVAST is overeager. You should now use the Disk Manager (diskmgmt.msc) to remove the drive letter from that partition. This will not affect the boot behaviour but it will silence AVAST.

{449f23b4-cd82-11e4-8a4f-485b39430625} does NOT show in the Register.  Why would there be a .sys file with 2 names?  Why would it be that large?  Why can't I get that file deleted and keep the one referenced in VSS?
