FAIL

This is basically a file archiving format nobody asked for, I guess.

I created this mostly because I wanted to practice with Python a bit. This is a file container that does nothing more than store the filename, its size, and the actual contents.

The name "FAIL" is from possibly all the things I've done so wrong making this, as well as all the things it doesn't support (like directories), and things I could have done better. But hey, I had fun.

I noticed this generates a larger file than a darc, huh. Maybe because of how I store filenames.

Usage

python buildfail.py myarchive.fail thing.bin *.zip game.3dsx
python extractfail.py myarchive.fail directory

Format

The file is layed out like this:

• Base header (0x8 bytes)
• File headers, one for each file (0x108 bytes)
• Contents of all files joined together

The offset of a file is calculated by getting the size of all the headers combined plus the size of each file before it.

Base header

Offset	Size	Description
0x0	0x4	Magic "FAIL"
0x4	0x2	Archive format version
0x6	0x2	Number of files

File header

Offset	Size	Description
0x0	0x4	Magic "FILE"
0x4	0x100	File name
0x4	0x4	File size
