cut and splice file?

[schrock.schrock]

does anyone know of a program (windows or mac) that i can use to split a file to portions of a specific byte size, then recombine with select portions of the original file?

example: split a 100 byte file to ten 10b files, then recombine part 1, part 3, part 7 into a new 30b file.

any help?

i could do it manually with a hex editor, but it is extremely time consuming for files that are 20-60 meg each, and i'd like something slightly easier.

tried, it doesn't work. but i did find a some split/join scripts in this hex editor (010 Editor for Windows) and i think it'll be ok now.

I'm pretty sure it will do that, Ive split files before and then rejoined them

it didn't work for what i'm doing. i'm trying to split the files with no outside influence.
i.e. when i split the files, winrar adds a small amount of data to the files in the form of compression data, original size, etc.

the hex editor is working perfectly. i don't need help with it anymore
