Server ‘c’ drive running out of space, what utilized most of disk space?

Issue

Sometimes windows based server shows disk is full, but actual Disk space usage is not fully utilized

Disk space can be consumed by various factors. There are many files are hidden and protected by system. Protected files can’t be viewed even you are the administrator and its mostly designed for security purpose. If you can’t see the hidden or protected files with Explorer, it doesn’t get added to the total size.

Resolution

The System Volume Information folder which is used to store some critical Windows components. Administrators group does not have any permission on the System Volume Information folder by default.

Step 1: Perform the following steps to gain access the System Volume Information folder.

Click Start, type cmd in the search box, right click the cmd.exe and select Run as administrator.

Type the commands:

  • takeown /f “C:\system volume information” /r /a
  • icacls “c:\system volume information” /grant builtin\administrators:F

Step 2: Please Collect Disk Utilization Output which can give a graphical on where the space is being used on the volume chosen.

Note: Please use Administrator account to log in as only administrator can access certain files.

On the affected computer, download and install WinDirStat from the http://windirstat.info/ , and run windirstat.exe.

Then please click Individual Drives, then choose disk “C”, then click OK. (Note: Please give a full view of the folder and files in system drive.)

final

Please check the folders which is much bigger and analyze it. My scenario temp folder utilized 53GB. So Cleaned temp folder and get 53 GB free space.
