When low disk space warning pops up in Windows 2008 server, it means that system C drive becomes full and there is not enough free space.

It may cause server reboot unexpectedly, system crash or data loss. When Low Disk Space warning message pop up and disk space is running low, 2 steps are most important – free up disk space and expand C drive as large as possible.

4. Empty or Decrease your Web Browsers disk usage for Cached files

Every web browser has a preferences or options area to adjust the temporary internet files and cache usage.

5. Remove Old Stuff

Just go into Add/Remove Programs or Programs and Features and tidy up. There’s likely a pile of old crap in there that’s taking up space.

6. Run Windows Disk Clean utility

To free up disk space in Windows Server 2008 r2, the best option is running Disk Cleanup which is a Windows native tool. It is able to remove most of junk and unnecessary files from your server fast and safely. Of course you may use third party system optimization software, but in my opinion, Disk Cleanup is well enough to accomplish this task.

Steps to free up disk space in Windows Server 2008 r2 with Disk Cleanup:

  1. Click Start -> Run -> type cleanmgr -> press Enter.
  2. Select C: drive and click OK.
  3. Click the check-boxes in front of the files that you want to delete.
  4. Confirm this operation.
  5. Repeat step 1 and click Clean system file in step 3.

If you cannot free up over 20GB free space, C drive may become full again in a short time, because new junk files are generated continuously. To completely solve this problem, you’d better continue the following steps:

  • Install programs to a separate partition, do not throw everything into C drive.
  • Change default download and cache path of the applications.
  • If you turn on Windows backup and restore point, don’t set it too large.
  • Delete caches and temporary files with Windows cleanup utility regularly.
  • Add free space from other partition and extend C: drive as large as possible.

Expand C drive as large as possible

To extend C drive in Windows Server 2008 r2, you’d better make a backup in advance and run safe disk partition software. Better than other tools, NIUBI Partition Editor has unique 1-Second Rollback, Virtual Mode and Cancel-at-well technologies to protect system and data. To resize partition and expand C drive, you just need to drag and drop on the disk map. After that, everything (except partition size) keeps the same with before.
