Yeah, pretty much figured that out by now, just one thing I noticed..

It seems DiskSpan only works correctly if there are no other methods set before it or there are External Compressors set for method before it.

I couldn't get it to work when setting the FreeArc internal methods such as M2, M3 or M4 before DiskSpan, it spits out an error.

Also, So far all the attempts I made in adding support for DiskSpan to my compression tool failed, it's basically a batch script (bat file), thing is Arc.exe keeps crashing when I'm making it use DiskSpan in my script, I can't figure out why.

UPDATE:
OK, Managed to get it partially working, it creates the .001 file when the size can fit in one archive but I get an error when it actually need to start to split (creating the .002 file), also, it seems arc.exe only crashes when there's no other external compressor defined before diskspan.
