Here's an example of an audiobook I'm having issues with.

viewtopic.php?f=124&t=4630899

it downloaded as "Sovietistan_Travels_in_Turkmenistan_A.m4b.001" and "Sovietistan_Travels_in_Turkmenistan_A.m4b.002" ,

I can't figure out how to play each individual file nor how to combine them in a full file.

Thanks in advance!

join both files with this free software hjsplit
