How to judge whether a driver is a floppy or a removable flash disk in C++?

Question

I wonder if there is an API to distinguish floppy and flash disk in windows, C++ And is it possible to link a flash disk to A:\? Many Thanks！

Answer 1

You can change the letters assigned to your drives somewhere in System Control, so the flash disk can be A:.

Use the OS API to query eg. the size of the disk, that should be enough to distinguish floppy and flash disk.

Answer 2

It is possible to link a flash disk to A:, but only if you have no floppy drives.
See Defining an MS-DOS Device Name for information about how to do this in a program.

You can determine whether a drive letter maps to a floppy device by using QueryDosDevice on the drive letter. Floppy drives will return "\Device\Floppy0" or "\Device\Floppy1"
