Some DOS users might want to know that Devuan version of ARJ is also working with Maemo Leste.

easy install:
sudo apt-get install arj

And it works also with multi volumes, so old floppy size option -v1440 is possible. Remember that original DOS arj volume max is 1 GB. But I didn't find the limit of whole package. I tested 4.7 GB file (at least it is over 32-bit limit) with option -v1G. So moving big files over FAT32 formatted memorystick is possible with arj.
