Secure Delete makes sure to overwrite the file or folder while deleting them. The method makes sure that all the unallocated portions belonging to the file are freed-up and available to use. It is true that Secure Delete can completely erase anything, but there is something it can’t. Certain folders that help in running the Windows system are excluded from the list. The list includes folders like: C:\Program Files, C:\Program Files (x86), C:\ProgramData, C:\Users, C:\Windows, and C:\Windows.old. The program will still work as it should inside the above-mentioned folders. The above folders are marked as exceptions because deleting them can lead to a fresh Windows installation.
