Here is a scenario: LogIn our software, the specified folder is shown, and logout our software, the specified folder will be hidden. Is it possible to realize it from callbackfilter? thanks.

Reliable hiding is possible only when your data is encrypted and is visible as a virtual folder when your software is running. Otherwise (if the directory exists on the disk), one can boot into safe mode and copy the data.

Virtual folder is possible in two ways: either using file system filter driver (but CallbackFilter can't do this) or using a file system driver that mounts a virtual file system to the given folder on NTFS volume (Callback File System does this).

Applications that encrypt folders, do this via custom file system filter drivers.

Sincerely yours
