Comment:
Well, "m:/" isn't a network share URL.  It's a drive-qualified path, and 
would normally be written "M:\".  But "M:\" isn't a network share, it's 
a drive that has been mapped to a network share.  A network share would 
be "\\host\path".

These can also be written as URLs.  I believe it goes like this:
"file://m:/" or "file://host/path".
