Why do large archive scans fail when the temp folder is set on a different drive ?

If the temp folder is not a folder on the C:\ drive (default is C:\Windows\Temp), you may receive a "failed to scan" result when scanning large archives and 8.3 filename convention is disabled.

To fix this issue, open an elevated command prompt (run CMD as Administrator) and enable the convention by running the following command : fsutil.exe behavior set disable8dot3 0
