Probleme Ordner beim Ordnersynchronisieren

Hi @KaGue 

Thanks for reaching out. 

Have you tried an alternate network connection? What is the file format and size of the files?

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences. 

Reset Procedure:
1. Close Lightroom.
2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom. 
3. Overwrite the Preferences when prompted by the dialog.
4. Close Lightroom.
5. Restart Lightroom.

Does the behavior continue after resetting the preferences?
If so, tell us about the drive you are using and where the folder you are attempting to synchronize resides. 
If you chose a different drive and folder, does it work?

Best,

Ranjisha
