# File Format

## Format Version 0

File extension is "*.simplearchive"

First 18 bytes of file will be:

    SIMPLE_ARCHIVE_VER

Next 2 bytes is 16-bit unsigned integer "version" in big-endian. In this case,
it will be zero.

Next 4 bytes are bit-flags.

1. The first byte
    1. The first bit is set if de/compressor is set for this archive.

The remaining unused flags are reserved for future revisions and are currently
ignored.

If the previous "de/compressor is set" flag is enabled, then the next section is
added:

1. 2 bytes is 16-bit unsigned integer "compressor cmd+args" in big-endian.
2. X bytes of "compressor cmd+args" (length defined by previous value).
3. 2 bytes is 16-bit unsigned integer "decompressor cmd+args" in big-endian.
4. X bytes of "decompressor cmd+args" (length defined by previous value).

The next 4 bytes is 32-bit unsigned integer "file count" in big-endian which
will indicate the number of files in this archive.

Following the file-count bytes, the following bytes are added for each file:

1. 2 bytes is 16-bit unsigned integer "filename length" in big-endian.
2. X bytes of filename (length defined by previous value).
3. 8 bytes 64-bit unsigned integer "size of filename in this archive file".
4. X bytes file data (length defined by previous value).
