Hello Mario,
it might be a good idea to add information in the help documentation on how to use regular expressions to make sure a string or file name does not contain a given substring.
I my naming convention a suffix character (a hyphen) signals that a given file is a derivative. If there is no hyphen in a file name, it's an original. So, for the master expression in Preferences - File Relations, I need a regex to check that there is no hyphen in the file name.
The regex I found to do this is "^((?!-).)*\."
So far, there is no support on how to do this in the help documentation, but I think it could help quite a couple of users.
Cheers, Stef
