How to disable Windows Server 2008 (R2) low disk space alert?
In Windows 2008 Server, if there is little free space in the system C drive, Windows pop up an alert about Low Disk Space, saying “You are running out of disk space on system C: To free space on this drive by deleting old or unnecessary files, click here…”
Windows create the low disk space warning to alert computer users when their hard drive is running low on available disk space. Windows 2008 Server low disk space will cause many problem, such as:
- System runs much slower.
- You cannot install any applications or Windows updates.
- System crash if extremely low free space remains.
You’d better fix this issue as fast as possible, as nobody wants to see the system crash, in that case, you have to start over keeping the server offline for a long time. To solve this problem, firstly try to free up some space and then expand c drive size. By freeing up space, you can disable the low disk space warning temporarily, but this warning may pop up in the future, because system update and files, applications and other files eat up the free space of C drive continuously. To completely solve this problem, you should expand C drive to larger size. To save time, you may jump to steps to expand C drive directly.
Free up space to disable Low Disk Space
Option 1: Delete Temp files
Click Start > Run, input “%temp%” or open directory step by step “C:\Users\Administrator\AppData\Local\Temp”
Option 2: Delete old Shadow Copies
Open “My Computer“, right-click C drive, select Properties, switch to “Shadow Copies” tab, delete old volume copies.
Option 3: Empty Recycle Bin and decrease the disk usage size
Empty Recycle Bin by right clicking it, but before this, you’d better open it to check whether these files can be deleted permanently.
To decrease the Recycle Bin disk usage size:
Right-click Recycle Bin > Properties, you can easily custom size.
Option 4: Remove Old Stuff
Uninstall the program you no longer use and delete the related files.
Option 5: Run the Windows Clean Manager
Windows comes already with a built in cleaner that does simple basic tasks to free up disk space.
To access it click Start -> Run -> type cleanmgr -> press OK.
Change the way running your server
- Keep data separate from the Operating System, one partition for Operating System, one partition for applications and the others for data.
- Change default download and cache path of the applications out of C drive.
- 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.
What to do if you cannot reclaim large amount of free space? Yes, the steps above are very useful for the server that never free up disk space, but to the server that is maintained regularly or the server C drive was created too small, you’d better continue to expand C drive. Otherwise, you’ll see Low Disk Space alert in Server 2008 in near future.
Server partition software is able to take free space from other volumes and add into C drive, so there will be plenty of free space to use.
