Microsoft .NET Framework 4.0 and Dokan library
To make a file system, an application needs to implement IDokanOperations interface. Once implemented, you can invoke Mount function on your driver instance to mount a drive. The function blocks until the file system is unmounted. Semantics and parameters are just like Dokan library. Details are described at 'README.md' file in Dokan library. See sample codes under 'sample' directory. Administrator privileges are required to run file system applications. Doxygen documentation is also available here.
Just run the bellow command or your file system application call Dokan.Unmount to unmount a drive.
dokanctl.exe /u DriveLetter
