expack(1) manipulate Flex files


expack -a FLEXFILE FILE...

expack -c FLEXFILE FILE...

expack -x FLEXFILE [INDEX]

expack -i MANIFEST

expack -l FLEXFILE


expack is a command-line utility that lets you extract and create Flex files. Flex files are archives (which means that they act as containers for other files, somewhat like directories) used by Ultima 7 to store most of its data. Note that the names of the original files are not stored in the Flex --- files are only retrievable by their index.

Modes of operation

-a Add
--NOT IMPLEMENTED YET. FUTURE ENHANCEMENT-- This command adds one or more FILEs to the end of FLEXFILE.

-c Create
This command takes one or more FILEs and bundles them into FLEXFILE, overwriting it in the process.

-x Extract
Lets you extract the files contained within FLEXFILE. If INDEX is given only the file at this position will be unpacked, otherwise all files are extracted. The created files will be named index.u7o.

-i Input
Similar to "Create", this command creates FLEXFILE from a number of input files. However, "Input" takes the names of the input files from MANIFEST instead of the command line.

MANIFEST must be a list of file names, one per line. The first name is that of the Flex file that is to be created, the rest are the input files used in building it.

-l List
This command lists the contents of a FLEXFILE. It gives you the number of files contained within the Flex file, as well as the length of each file.

Adds bee.wav to the Flex file animals.flx.

expack -a animals.flx hamster.wav snake.wav donkey.wav

expack -c animals.flx duck.wav cat.wav cow.wav dog.wav

expack -x text.flx 17
