Create a virtual filesystem on Windows - now in user-mode
Callback File System is a library (SDK, software development kit) for presenting various data as files and directories of a local virtual disk. Regardless of where the actual data are kept: in files, in database records, memory, or elsewhere - they will be treated as if they were parts of a single file system.
Callback File System consists of pre-created kernel-mode drivers and a user-mode API available for .NET, Java, C++ and VCL (Delphi and C++Builder).
What Callback File System offersCallback File System provides a ready-to-use file system driver which routes requests going to the filesystem to your user-mode code. Your user-mode code receives the requests and processes them by accessing or modifying the actual data that reside anywhere you need. Also you get a user-mode API (libraries), which is used to manage the driver and process its requests.
