Something I've discovered:
Windows has a limit of 2047 characters in a single command-line prompt. This mostly comes into effect when sending a lot of books to an "open with" action. (This is why I usually run Power Search first,
then send the files to Ransack.)
Code:
Traceback (most recent call last):
File "calibre_plugins.action_chains.action", line 237, in run_chain
File "calibre_plugins.action_chains.chain_tools", line 120, in run_loop

FileNotFoundError: [WinError 206] The filename or extension is too long
I doubt there's much to be done about this, aside from providing a more informative dialog.
