How to Clean Up “System Volume Information” Folder

One of the servers (working Windows Server 2012 R2) has run out of free disk area on a system drive (C:). I checked and cleaned all resource-consuming places (, TEMP folders, person profiles, , and many others.), however it didn’t give a noticeable impact. There was nonetheless not sufficient disk area. At final, I’ve discovered that a big a part of a system disk has been occupied by System Volume Information folder. In this text I’ll strive to inform you how the System Volume Information folder is used on Windows programs, what’s saved in it, and the way to clear up it.

Note. The directions given on this article are relevant to different Windows variations as effectively: Windows 10, Windows 7, Windows eight.1, Windows 2008 R2 and Windows 2016 / 2012 R2.

How to Gain Access to the System Volume Information Folder?

The System Volume Information folder is situated on the root of every disk (be it a neighborhood HDD / SSD, or detachable USB flash drive). It shops system knowledge associated to system restoration service, indexing, File History characteristic, and many others.

By default the System Volume Information folder is hidden and solely the SYSTEM has entry to it. Even the administrator can not open it and look at the contents of the folder. If you strive to open the System Volume Information folder in Explorer, underneath any person (even an administrator), you’ll obtain an entry denied error:

Location isn’t accessible.
C:System Volume Information isn’t accessible.
Access is denied.

To view the contents of the folder, you might have to assign your self because the listing proprietor and grant your account the NTFS permissions to entry it (this may be finished by way of the Security tab within the folder properties). But a lot quicker, you’ll be able to grant your account (for instance, username) permissions to entry the folder with the command:

icacls "C:System Volume Information" /grant username:F /t

Check within the folder properties on the Security tab that your account has full entry permissions to the folder.

To prohibit entry to the System Volume Information folder, run:

icacls "C:System Volume Information" /take away username /t

What is System Volume Information Folder Used For?

What is saved in System Volume Information folder? I discovered details about the next providers, which retailer their information on this folder (the record isn’t exhaustive):

  • on consumer programs or System State backups made utilizing Windows Server Backup (wbadmin) in server OSs;
  • The content materials of Indexing Service database used for quick file search;
  • Distributed Link Tracking Service database;
  • Disk snapshots made by Volume Shadow Copy, which can be utilized to get better older variations of information.
  • ;
  • The database of file service;
  • DFS Replication database (dfsr.db).

If you utilize shadow copies in your laptop or server to roll again to previous variations of information / system states, take note: every new VSS snapshot saves knowledge to the System Volume Information listing, growing its dimension. The extra usually shadow copies are created and the extra usually the information on the disk change, the quicker the scale of this listing grows.

In the screenshot beneath, you’ll be able to see that within the System Volume Information folder there’s a system file bigger than 160 GB.

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

Note. It isn’t advisable to manually delete information in System Volume Information folder, because it shops info wanted to restore the system and different essential info.

You can radically clear up the System Volume Information listing by disabling the system restore factors and file historical past. But this isn’t at all times permissible.

Firstly, let’s see what’s saved on this listing. Display the statistics of utilizing shadow copies:

vssadmin record shadowstorage

vssadmin 1.1 – Volume Shadow Copy Service administrative command-line device
(C) Copyright 2001-2013 Microsoft Corp.
Shadow Copy Storage affiliation
For quantity: (E:)?Volume
Shadow Copy Storage quantity: (E:)?Volume
Used Shadow Copy Storage area: three.08 MB (zero%)
Allocated Shadow Copy Storage area: 896 MB (1%)
Maximum Shadow Copy Storage area: 19.zero GB (29%)
Shadow Copy Storage affiliation
For quantity: (C:)?Volume
Shadow Copy Storage quantity: (C:)?Volume
Used Shadow Copy Storage area: 912 MB (2%)
Allocated Shadow Copy Storage area: 1.20 GB (three%)
Maximum Shadow Copy Storage area: three.98 GB (10%)

As you’ll be able to see, 10% of system drive area C: is allotted for snapshot information and solely 2% of which 2% is occupied. If the worth of Maximum Shadow Copy Storage area is ready to UNBOUNDED, it signifies that the restrict for shadow copies isn’t set and so they could occupy all free area on the disk. By default, the system provides 10% of the whole disk area to retailer this knowledge.

You can cut back the disk utilization restrict by VSS to 2 GB utilizing the vssadmin command. The vssadmin command has the next syntax:

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

In our instance it should appear to be this:

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

vssadmin 1.1 – Volume Shadow Copy Service administrative command-line device

Successfully resized the shadow copy storage affiliation

If you create system state backups utilizing Windows Server Backup, the all previous system state copies may be deleted as follows (within the Windows Server editions):

wbadmin delete systemstatebackup -keepversions:zero

When you run the wbadmin delete systemstatebackup command in Windows 10, an error seems: “The DELETE BACKUP command isn’t supported on this model of Windows“. The truth is that in consumer programs (Windows 10/ eight.1/ 7), administration of restoration factors and limits is feasible solely from the GUI. Open the System properties and click on on the System Protection tab.

By urgent Configure, we proceed to the settings of quotas for restore level storage. You can delete the prevailing restore factors right here.

Select the system drive and click on the Configure button. The quota configuration dialog field for storing system restore factors will open. You can cut back the scale of the disk for storing shadow copies. Here you’ll be able to both delete all present restore factors (Delete button), or utterly disable the creation of restoration factors by choosing Disable system safety.

To cut back the scale of the System Volume Information catalog you may also:

  • Move the VSS knowledge to one other NTFS drive (vssadmin add shadowstorage /for=c: /on=d: /maxsize=30%);
  • Disable or reconfigure the Windows File History characteristic;
  • Perform system cleanup utilizing the built-in utility – cleanmgr.exe;
  • If you utilize the information deduplication, you will need to disable deduplication and run the file de-optimization command: Start-DedupJob -Volume D: -Type Unoptimization (the command could take fairly a very long time, additionally be sure that the disk has sufficient free area).
