You know, the problem here is something else completely: your proc is expecting a list of file names. Instead it gets a string containing a single file name.  So what happens is that the foreach loop takes that string, splits it into a list at each space character, and processes each part separately. So "$::env(SystemRoot)\my dir" turns into "$::env(SystemRoot)\my" and "dir" as you see in your output. You don't want this implicit conversion.
Instead, turn your input into a proper list before calling your proc above and all should be good.
