Adding files to the format type ".jef+"

Permalink
Hi!
I have a problem to download and use a file format ".jef+".
Concrete5 removes the "+".
I found the save, and read, function format and added to the exception "+".

const REGEX_INVALID_EXTENSION_CHARS = '{[^a-z0-9+]}i';

The file is now loaded, but then again removed "+".
Where else would you need to add an exception "+"?

Have you tried adding the file type to the Allowed File Types in System and Settings?

in Allowed File Types in System and Settings I added.
But now, when i add a file, the C5 remove "+" of its format.
