Liu Chang asked a very similar question to this one here, Linux equivalent of the Mac OS X "open" command.
Is there a windows equivalent for the Mac OS X \"ope
The closest thing available is start.
start
If its first argument is double-quoted, that argument is treated as a window title rather than a filename. Thus, to use it robustly, add an empty string as the first argument:
start "" "my filename.foo"
Thank you to @Holger for pointing this out!
