Shell on device, file path dumb question

I'm trying to shell word to read test text.txt on the device in \My Documents\bapps

shell ("pword.exe","my documents\bapps\test text.txt")
shell ("pword.exe","\my documents\bapps\test text.txt")
shell ("pword.exe","\bapps\test text.txt")
shell ("pword.exe","bapps\test text.txt")
shell ("pword.exe","test text.txt")

all return the same file could not be opened error

How does one phrase file paths on the device please?
:sign0085:

I 've tried this:

Shell( "pword.exe" , "my documents\bapps\test text.txt")

and it works.

Is it possible that the actual file name is not "test text.txt" but has an extra blank in it ?
