It is up to document reading program, will it read such file, or not. Only few programs are clever enough, to skip the JPEG data and find the place (inside the file), where document data begins. It is NOT a normal behavior, if program does that tricks, so there is no guarantee, that the file will be readable. (You have to check first) Most programs will just sniff the file beginning (where JPEG data starts), and say "Aha! This is not my document! I will not work with this!" So, use this at your own risk :) Always check, if the file is readable after such transformation. When you use command line

copy /b File1 File2 DestinationFile

you actually make a file, which contains File1 data File2 data.

Was succesfully hidden in the JPEG file (meaning, after renaming to PDF, the file did open). I made a test with a DOC file. Did not work (after renaming the generated file, this could not be open by MS Office). I made a test with a MP3 file. Almost work (after renaming, the file could be play with WinAmp, but not with MediaMonkey or BSPlayer, while the original could be played). I don't know what it works for others. So, don't rely on this method untill you check that the file-to-be-hidden can be extracted from the generated file. ;) I made a test with a PDF file.
