How do i emulate a storage card?

[Ranhiru]

I have seen in many programs such as FreeOTFE that they can emulate a storage card in WinMo. It will be shown in Windows Mobile just as a storage card is inserted and i can interact with it just like a SD Card.

How do i implement that? Any tips/tricks/guides/samples?

I am using WinMo 6 Professional with Dot Net Framework :)
I know i have to use C++ with some Native APIs :) But i need to know which ones :(

Thanx a lot in advance :)

Is this on the emulator, or one the actual device?

On the emulator and the physical device both :)

I think i now what you are getting at, emulating a storage card using a shared folder in the emulator.

That is actually not what i want :)

Software like FreeOTFE enables to emulate a virtual storage card. I know there is no one command to instantly emulate a storage card.

Hmm.. I'm not too sure. I can't see why you would ever want this. Is there a piece of software that needs a memory card installed, but you don't have/want one installed?

Actually the case is that i want to create a mobile equivalent to TrueCrypt (Not as advanced though). FreeOTFE is something quite similar to TrueCrypt for WinMo. Although all the files are contained in a single container file, it provides a virtual storage card (acts as a REAL SD card) that acts as a middleman to carry out file operations on the fly. Everything that you do in the SD card (virtual) is carried out on the container file. The virtual storage card exposes everything in the file.
