Different from the ones I'm used to. A quick look doesn't show much of a normal index but file names may be stored at the end of the file.

Different from the ones I'm used to. A quick look doesn't show much of a normal index but file names may be stored at the end of the file. This could be a bit tricky but only two ways I can think of this working is it stores the start offset of the file name for a specific entry or it loads all file names into memory.
File offsets may just be of a 'long long' data type, which is a 64bit number stored over 8bytes rather than 4bytes of padding. I wonder I could just use as streamoff. That's typedef as long long... right? O.o
Filenames are null terminated/separated by a 0x00 and might not have any whitespace in the filename/path since looks like they used underscores like most people do. XD
There is a little bit of data before or after each data entry. Unsure what it means right now.
