Custom folder paths for exports on Windows

[t3dotgg]

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• [X] Check out all the menus and keyboard shortcuts. Maybe the feature already exists?
• [X] Try with the newest version from GitHub
• [X] Read the documentation and FAQ, Known issues, Troubleshooting to see if the feature already exists
• [X] See if someone already suggested this under Issues or Discussions

Description

I cut an issue about bad folder directories being created on Windows awhile ago https://github.com/mifi/lossless-cut/issues/1790

Just set up a new PC and updated to latest Lossless-Cut. Didn't realize I wouldn't be able to export to per-segment directories anymore :(

Ideally I'd still be able to use (dynamic) folder names on Windows. If not, I think a better error here would be nice.

Also thought that turning off sanitization should let me do this still :(

Hmm, I just tested on windows 11 and I'm not getting this error on 3.59.1 when including a slash, and it's correctly creating the clips directory for me.

What I'm suspecting is that one of your segments' SEG_LABEL variable contains disallowed characters. If you click on Preview button, what do you see as "resulting file names"? on windows, when sanitize is "off", the following characters are not allowed: '<', '>', ':', '"', '|', '?', '*'

I think a better error here would be nice.

I will improve the error message to specify exactly which characters are invalid.
