Hi. I bought some software for MS Flight Simulator today which involved a very large download (over 10GBs) - I left it running whilst I went to work. I had 13.5 GBs left on my C drive (one of 2 partitions on a 128GB SSD) so figured all would be OK. When I returned 10 hours later, the download had failed, as, apparently, my C-drive was full. No idea why - I know there was enough room for the 10GB download. I could only guess that some temp files were downloaded at the same time (??).
The problem now however is that after deleting my browser (Firefox) cache, running the Disk Cleanup from Properties/Tools for C drive, I still have only 3GBs left. What happened to the 13GBs space I had this morning? What else do I need to clean up? Tried a System Restore - no change.
I noticed that my ProgramData folder (hidden) is over 12GBs - most from the indexing service (Microsoft/Windows/Search), but that would have been there before today. (I've disabled the Windows Search service and moved that folder to an archive on another drive - I use a 3rd. party search engine, SearchMyFiles, for my PC, which is much faster than the Windows Search in any case).
Having removed the Search folder, if I show hidden files & folders, then select everything in the C Drive, sys files and all and then show 'Properties' - I still get some 4GBs less (28GBs) than is recorded in the Properties box when right-clicking the C-Drive root (32GBs) - where's the difference? I haven't run checkdisk yet, but before I do is there any obvious area I need to clean to regain the 10GBs I lost today?
