Comment 2 for bug 825092

I have the same error on Windows too. In fact I have received the error about dozen times already. Twice for about ten seconds qBittorrent was doing nothing but showing the notifications in the tray.

I can't confirm John Doe's conjecture above about file name length. In my case full file name is 73 (ASCII) characters long. That is far far below even the Windows' PATH_MAX.
