No luck.
Placed two sequential calls inside the batch file:
Code:
py -3.4 KindleButler.py "%~dp0one.azw3"
py -3.4 KindleButler.py "%~dp0two.azw3"
First call proceeds and completes, message window sits onscreen and does nothing. Force closing window, getting new window with truncated message "Used by another process".
Well, placing each call into separate batch, running first batch and while progress bar running starting second batch. Getting encouraging message Queue:1... and everything terminates with infamous "Used by another process".
How correctly fill a queue of input files?
