Right clicking on file folders under the Windows directory and choosing Properties, Temp, CbsTemp, tracing, and ToastData, , initially say over 20 GB big, openeing folder, says it is empty, right clicking and properties again, says folders are empty.
I tried renaming then replacing the folders then deleting the renamed original does not help.
I went to work with over 3 GB space left, came home and had less than 700MB.
Got on the intenet to look for solution, logged off, erased several hundred MB of files, then had less than 600 MB!
windirstat is no help in finding expanding file folders.
Thank you for any help you may provide!
