Can you make use of a name space handler in some way?

That's an idea, but I presume it requires a driver to be installed, and is not be flexible in size. The audio files could be any size.

I think I'll be giving up on that idea. It's working OK as it is really. I'm decrypting the audio file before it plays and storing it with a .DLL extension and hidden & system file attributes in a completely different folder, so I think this will do.

Would using a RAMdisk be good enough?

I doubt this is possible but I thought I would ask anyway.

I have a 3rd party DLL which opens a file that I specify. Specially it is
an audio decoder plugin which decodes MP3 to PCM.

What I would like to do is use this plugin to access a memory location which
contains MP3 data instead of a file.

Is it possible to set up something in Windows where you specify a filename
but actually accesses memory instead.

This will be used with encrypted mp3 files so they are not accessible to
anyone to steal for their own use. I am currently opening the file,
decrypting, and then saving a temporary file to disk. But this has 2
disadvantages. It is very slow, so lots of latency between asking a track
to play and hearing it. And also, while the file is decrypted on disk,
someone can steal it.

The DLL cannot be modified. Is there any solution?

Thanks,
Ross.
