How should file extensions related to Include/Exclude be formatted?

The formatting of file extensions related to Include/Exclude should follow specific guidelines for correct identification by the system. When file extensions are separated with a hard return, it allows each entry to be recognized clearly and distinctly by the processing software, ensuring that there are no ambiguities in interpreting the list of extensions. This method of separation maximizes clarity and minimizes the potential for errors during file processing.

Using a hard return also supports the organization of data in a way that helps users quickly scan through the list, ensuring that each entry is treated individually rather than as a continuous string of characters. This approach is especially useful when dealing with a long list of extensions, simplifying the inclusion or exclusion process.

The other formatting options, such as using commas or requiring lowercase letters only, would lead to potential misunderstandings or misinterpretations of the file types being specified. By adhering to the hard return format, users can ensure that the file processing system accurately recognizes all specified extensions without any confusion.
