I recently had the opportunity to trial Callback File System (CBFS), a software component that can be used to present various data as files and directories of a local virtual disk. This software proved to be incredibly versatile; regardless of where the actual data resides - be it in files, in database records, memory, or elsewhere - it will still be treated as if it were part of a single file system.

I was particularly impressed by how simple the process was with CBFS. With this component, it is possible to create your own file system within the application you develop - ultimately, this can be exposed to Windows as a virtual disk, or as a folder of existing disk. Surprisingly, it requires no kernel-mode development to implement your own file system, either.

What’s more, developers can use C++, C#, Visual Basic .NET, Delphi or even Java to build a file system that exposes any data. This approach lets you offer information stored in the database or across the network, all as if they were files on a local disk.

All in all, I found this software to be a comprehensive solution offering an increase in functionality, which is both easy to use and incredibly effective. If you need to present and interact with data as if it were part of a file system, CBFS is definitely worth considering.
