d disabled, you cannot copy and paste files not only to removable drives but even within partitions and folders. And because the clipboard is disabled you cannot even copy text. The protection feature can be activated or deactivated only by providing the correct password.
When the application is active you are allowed to copy and move files via the built-in file-copier. The software also protects against file deletion and renaming, but this is in a separate section and you have to apply this setting to individual files and folders, which isn’t very helpful.
The program however suffers from a serious flaw – it can’t prevent copying using drag and drop. This is because M File Anti-Copy prevents file copy by disabling the clipboard. Since drag and drop does not use the clipboard, the program fails. You can still use it and just hope the users don’t discover the loophole.
M File Anti-Copy also provides some additional protection like disabling the Task Manager and regedit.
Prevent file copying is never fool proof, there always be some workaround. The best kind of protection will be to disable all removable drives through either the BIOS or the registry editor, and disconnect the computer from the network to prevent file transfer. Or simply deny physical access to the computer when you are not around.
