I've recently been going through sample workflows on designer, but for some reason, I can't seem to understand the purpose of the dynamic input tool. I somewhat understand its purpose in regards to SQL queries (It works similar to that of a vlookup/join), but when it comes to using it with a directory, I'm having trouble understanding its purpose. I understand that the directory tool looks up all files in a desired path, but I can't seem to understand what changing the entire file path with the full path does. Does anyone know of an example that would make this easy to understand?
