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.
