Some ARJ files can be parts of a multi-volume sequences. In ARJ you can split a huge archive to a few smaller files, which are called volumes.

- .arj for first volume
- .a00, a01, a02 .... etc. for any additional volumes
In order to unpack the multi-volume ARJ archive, you need to place ALL of the split parts in the same directory and start extraction of the first volume (.arj). The program will automatically use all of the parts to extract the content of the archive.
