I have googled the issue and it is suggested to start with internet temp files, which I did, but it didn't make that much difference. Thanks for any and all advice.
In fact, on Server side, it's the log file that takes much disk space. These log files size will continue to accumulate when Server is running, deleting them will free up large capacity, and you'll be surprised when you say that much free space you just made. like another user from serverfault.com said:
I was able to finally get enough disk space by deleting IIS logs , and we're impressed that he mentioned:
I was able to free up close to 5GB in Windows patch files.
Since the log files will gaining its 'weight' as times goes by, deleting them for once will free up some disk space, but next week we have to do it again. If you want to extend this interval, extend C Drive.
Not in Disk management but in partition managing software which will keep data safe during extending. Download Partition Expert and we'll go into detailed steps:
- 1. Run the 32-bit or 64-bit portable software, in the disk-map of Server system, we can find that C Drive is in low disk space, but D or E Drive are rich in free disk space, so we click on D Drive first.
- 2. Run Resize Move Volume operation and resize partition wizard window will open. In this window, we can drag the handle on the head inwards to create free space. Please don't worry, creating free space won't damaging data on the disk. Click OK to close this window.
- 3. Check the disk map again, free space is created on the disk. Now we click C Drive and run Resize Move Volume too. This time we drag the right-side handle outwards to merge free space. Click OK and Commit to extend volume.
