Segmented download fail with longer filenames

When you try to download a file with a longer name on windows, you sometimes encounter a access denied error. But it's not because of the permissions but because the folder and .cyberducksegment file just break the windows (or maybe NTFS) name limits.

For example I bought an Album and want to transfer it from my Server. The filename is

13. RoughSketch feat. DD”ナカタ”Metal — Booths of Fighters (Camellia's ''''Barrage of Flurries'''' Remix).flac

Creating a file on windows with that name is no issue.

But if you try to create that file in a folder called

13. RoughSketch feat. DD”ナカタ”Metal — Booths of Fighters (Camellia's ''''Barrage of Flurries'''' Remix).flac.cyberducksegment

like cyberduck tries to you get an error because the name is too long, so cyberduck fails to download the file. So without renaming the file on the server I have no chance to download it even though it should be possible. This is compounded by the issue that the .cyberducksegment extension is really long so you encounter this issue a lot earlier than with a shorter file extension.

I'm having the exact same issue that's listed here. I get "Please verify disk permissions". The error goes away if segmented downloads are turned off.
