You're welcome
About your questions, i'm sorry for being little slow here, but I don't understand fully
Are you talking about 'deluge-console add -p 'folder with space' foo.torrent'. In that case, then on linux you can use globbing, so 'deluge-console add -p folder* foo.torrent', but that is probably the shell expanding those globs and so not available in windows command-prompt(atleast not 10 years ago when I last dabbled in windows) - I know deluge has some globbing built-in too, but i'm guessing it's the shell here(zsh/bash etc), but not 100% sure.
The changing of torrent-name in GUI is a known issue of that plugin sorry and I don't know how to fix sorry(I don't even use that plugin either
).
If you don't seed, although "rude", then you can make an execute script which drops the top-folder afterwards, but again, I don't know at top of my head how it's done on windows.
If you tell me what app you're trying to integrate with deluge-console, then maybe I can help you better?
