crates.io cli crates.io lib

A rust implementation of the openmw bsatool.

Note: Currently this project only supports BSA files compatible with TES III: Morrowind.


The easiest way right now is to install with cargo:

cargo install bsatool_rs


There is also a library option for manipulating BSAs from other rust code available on crates.io and can be added to a project with:

cargo add bsatoollib

Example Usage

use bsatoollib as bsa;

// open an existing BSA file
let bsa = bsa::BSAFile::new("SomeFile.BSA").unwrap();

// print all file names in the BSA
for file in bsa.get_list().iter() {

Command line options

> bsatool_rs --help
