Obviously, the simplest way would be to write the parameter "correctly." However, this comes through a procedure that allows the user to load one or more paths to add to those defined in the script, meaning it's not up to me. As I said, I tried several solutions, but they didn't work: automatically converting the parameter to a list, using the file normalize and/or nativename commands, or, as a first idea, checking whether the parameter is a list or a string (spoiler: in TCL, everything is a string...). Having said all that, I hope I've clarified the point of the question, and again, thanks for answering.

If what you want is a way to unmangle a mangled filename, I would say there is no reasonably simple way to do this.

If there are only a few valid directories to choose from, and you can generate a list of them, then an "almost equal" function might do this, but likely not with 100% accuracy.

I have an application uses a fuzzy string compare function that produces a value that is a measure of a near match. I got the idea and some code from here, in particular I use the trigrams function:
