MultiEx BMS Script

The BMS script given below will extract and replace files. A limitation for this script is that you are only able to replace on file at a time to avoid making the archive corrupted. I.e. load the archive in MultiEx Commander, replace a file (if you'd like) and then re-open the archive to replace another one.
