I was eyeing AudioApp example and saw that it uses inside the function
MoveFile(), which i have never heard of. I have read of
CopyFile() and
DeleteFile() and remember wondering how come there is no "move".
It must have been undocumented since BrightSign beginnings, since their examples uses it too. In any event, seems this function is a kin of
CopyFile() and should be documented around there. Here is example showing it is one of the global's:
BrightScript Debugger> ? global.moveFile("", "")
false
