For example, if I want to merge a.jpg and b.mp3 into c.jpg, and then split c.jpg back into a.jpg and b.mp3, how should I do it?

Splitting: under DOS you can use a pctools utility to split files; under Windows you can use ultraedit

First package the MP3 into RAR format copy /b jpg.jpg+mp3.rar filename.jpg [ Last edited by chishingchan on 2008-1-3 at 08:54 PM ]

DOS's own commands probably can't do file splitting; the result of copy/b is inseparable. Without auxiliary information, there's simply no way to find the merge point
