How to Clean Up System Files in the System Volume Information Folder?

Note. It is not recommended to manually delete files in System Volume Information folder, since it stores information needed to restore the system and other important information.

You can radically clean up the System Volume Information directory by disabling the system restore points and file history. But this is not always permissible.

Firstly, let?s see what is stored in this directory. Display the statistics of using shadow copies:

vssadmin list shadowstorage

Shadow Copy Storage volume: (E:)\\?\Volume{5a419164-9eba-11e5-84c5-004046bbefbb}\
Used Shadow Copy Storage space: 3.08 MB (0%)
Allocated Shadow Copy Storage space: 896 MB (1%)
Maximum Shadow Copy Storage space: 19.0 GB (29%)

For volume: (C:)\\?\Volume{843c6330-9866-11e5-80b3-806e6f6e6942}\
Shadow Copy Storage volume: (C:)\\?\Volume{843c6330-9866-11e5-80b3-806e6f6e6942}\
Used Shadow Copy Storage space: 912 MB (2%)
Allocated Shadow Copy Storage space: 1.20 GB (3%)
Maximum Shadow Copy Storage space: 3.98 GB (10%)

As you can see, 10% of system drive space C:\ is allocated for snapshot files and only 2% of which is occupied. If the value of?Maximum Shadow Copy Storage?space?is set to UNBOUNDED, it means that the limit for shadow copies is not set and they may occupy all free space on the disk. By default, the system gives 10% of the total disk space to store this data.

You can reduce the disk usage limit by VSS to 2 GB using the vssadmin command. The vssadmin command has the following syntax:

vssadmin resize shadowstorage /on=[drive letter]: /For=[drive letter]: /MaxSize=[maximum size]

In our example it will look like this:

vssadmin resize shadowstorage /on=c: /for=c: /maxsize=2GB

vssadmin resize shadowstorage

If you create system state backups using Windows Server Backup, the all old system state copies can be deleted as follows (in the Windows Server editions):

wbadmin delete systemstatebackup -keepversions:0

wbadmin delete systemstatebackup -keepversions:0
