Join 2 files together

I am working on a high powerful (but INCREDIBLY slow) compressor (or is it -er). I've managed to compress a 2MB file down to around 200 Kb. It's really good for compressing single files, but being able to compress multiple files into one file is pretty much the whole point of these archiving programs (like WinZip and WinRar and WinAce).

My point is, is there any way to put two files together? Opening it up using the Open "C:\Test.txt" For Input As #1 isn't exactly the best way to go because it doesn't open JPEG files properly for some reason.

I also need to put some characters in between to seperate the files (maybe 16 null characters or something).


Thanks to anyone who can help.

Why don't you open the files as binary instead?

If you want to stick all the files together, you could create an area at the beginning of the file that details where each file starts and ends, so that you know how to split them up afterwards.

I didn't even know about this binary thing. Stupid me.

But the thing is, how will I tell if the information is part of the file, or the information about the file?

Is this what you want?

Thanks Matt. It's close to what I want, but I have to read each byte seperately. I'll work on it from here.

Thanks guys (Harry and Matt).
