FileBot

I tried to rename files off sshfs using filebot gui and choose a simple format. It successfully rename but upon checking on the folder. It produced quoted filenames eg. 'lost.301.mkv' All episodes were named like that. This only happens when renaming files on mounted sshfs. Is there way to fix this undesire effect quoted filenames?

You'll have to ask the developers of sshfs about that.

From an applications point of view all files are the same regards of the internal filesystem implementation.
