Can/should (exclude) path masks on Windows use backslashs?

Using your .NET interface, is this a valid exclude path mask for a local path?


Or should I rather write something like this


Or maybe even?


My goal is to exclude everything below the path "c:\Backup-ToExternal\Full".

Most likely my question is way too simple to be answered here at all.

Could at least someone give me a pointer on how to do my own research?

Unfortunately I found zero examples and zero documentation on how to do what I want (i.e. specifying a full local path)

This first syntax is correct.
