Filesystem operation filtering - now in user-mode

CallbackFilter lets you achieve functionality of filesystem filter drivers in user mode, right in your .NET, C++ or VCL (Delphi) application.

What CallbackFilter offers

CallbackFilter provides a ready-to-use file system filter driver (not a minifilter driver) that intercepts requests going to the filesystem and calls your user-mode code. Your user-mode code receives the request and can process or deny it based on any criteria you like. In many cases you can also alter the data being read or written from/to the disk. You can even create virual files and directories.
