User mode file system for Windows
Dokany is the fork of Dokan, a user mode file system library that lets you easily and safely develop new file systems on the Windows OS. When creating new file systems on Windows, you need to develop a device driver that works in the kernel mode on Windows-- a difficult task without technical Windows Kernel knowledge. Dokany makes it easy. It enables you to create these file systems without device drivers, and is completely free to download. It is similar to FUSE, and also offers compatibility with a FUSE file system.
