Windows disk info shows used space that I can't find
Solution 1:
Selecting all files and showing properties skips files where your user accound doesn't have access to while showing the disk pproperties reads the NTFS meta data and always shows the correct usage.
Run TreesizeFree (as admin) to see a better view of the disk space usage. Running as admin shows hidden folder like System Volume Information where system restore points and chkdsk logs are stored.
