I have a few files in pdf format with the "/" character which they will not sync. getting an error
payment 2?28?17.pdf.FnILj5" failed: Invalid argument (22)
It appears the / is not recognized. If I change it manually to a . it will recognize and sync. any way to batch change those pdfs?
In Linux you can't have a '/' character in a filename as this character is used for folders. So you have to rename the files before syncing them to a Linux file system.
I don't know about scripts in MacOS but there is certainly a possibility to rename all your files with a script (e.g. to month_day_year...). If you can't do it yourself you could find help in the Super User community.
