Windows.old cleanup recovery-amount mystery
I decided to commit to the Windows 10 upgrade and get rid of the Windows.old folder, which was very large. After I ran the System Files Cleanup option in Disk Cleanup, it reported that I could gain over 18GB by proceeding. So I did, and the Windows.old folder disappeared. However, my free space increased by only about 3GB. I am totally bewildered by this result. I would really appreciate it if someone could provide some insight.
One of my guesses is that Windows 10 was using some of the files in Windows.old, and that, before deleting the files it does not need, it copied the ones it does need over into the Windows folder. Another guess is that the Windows folder was compressed and that is no longer. It is now about 11GB. My vague memory is that it was about 7GB before.
I took a look around with Windirstat, and I could not see anything strange.
This little notebook only has 27.8GB of available on-board flash for bulk memory, of which only 5.3GB remain free. I can account for about 3GB of stuff I have installed; but I was hoping for a bit more head room. I have installed a 32GB SD card; but I would prefer not to have to use that to install programs. (I expect to use it for media files.)
