Windows Server 2012 C: drive - files vanish

Windows Server 2012 running MS Exchange. Server has been stable for years.

Space on C: was getting tight. I just went to manually clear 5 GB  from the inetpub log file folder. Normally this is not an issue.

The files are removed from the folder but they did not move into the Recycle Bin. C: drive does not register that the files are deleted. Properties on inetpub folder show that the data is gone.

I ran Disk Cleanup. This freed up 400 MB. After this, I tested removing files from C: and they went to the Recycle Bin this time, and I was able to empty the bin, and that space was reclaimed on C:.

However, the original 5GB of logfiles have vanished, and the space is not reclaimed. Where did the files go? I need to reclaim this space on C: ASAP.

Could you have accidentally moved them to a different folder when you tried to delete them?  Have you tried doing a search for any of the names of the files you tried to delete?

I'd download and install Treesize (from ) to survey how much space is taken up by each folder.  That will help you sort out what else to get rid of in addition to possibly locating those files.

Thanks for the TreeSize tip. It showed 6 GB in the Recycle Bin -- but the Recycle Bin icon was showing empty, and the "Empty"
 option was grayed out.

I cleared Recycle Bin with TreeSize and the space is now reclaimed. Thanks!
