Package multipe files in one. Resource management?

Hello,
I want to make a custom program for packaging multiple files in one. Not as complicated as ZLIB or others. Consider few files, XML, txt, JPG, OGG, I want them to be added in 1 file. Not visible not readable. Just a datafile. I have some ideas about creating some kind of indexing of the start byte, end byte of each file. But I am still way too far. Can you point me some direction at what should I stress in creating this software. It will be portable since I am planning to use stdlib, stdio only, maybe and string to recreate the filenames from the large chunk datafile.

Have you looked at the TAR format? Here is a link. If you want to make a custom format that may give you some ideas.

GNU tar 1.28: Basic Tar Format

By the way, ZLIB is not really meant for packaging multiple files. It is only for compression. I really think TAR is what you want. If you don't want to make it yourself there are also ready solutions available like PhysicsFS PhysicsFS

Thanks, I saw it. It appears it won`t be a few-hours-fun-job to make such a thing. PhysicsFS is quite good. It`s actually ready and downloadable with .h/.c files. Tar however looks quite complicated, but have the things I need. It genereate files form the chunk and vice versa. My idea was to read files into memory, then dump them into a single file. For now this is my target, re-generate of the files form the chunk will be the next step. I`ll look into PhysicsFS .c file to see if I can get some clues.
