I’m wondering if it’s possible to emulate a partition or, preferably, a directory, without a need to develop a filesystem driver. And this partition is visible to Windows and other applications, works like a regular directory or partition, but I/O is under my app’s control – I override read/write/open/close/list functions for that particular directory so I can supply information to the OS of how many files and directories inside the directory, their sizes, filenames and etc.

Thank you in advance
