it doesn't recognize, it automatically tries to download it.

.rm files so we have to trick it
into welcoming their data onto the screen. We do this by creating
a metafile, ending with the extension .ram.

.ram file it goes and gets the file listed in the metafile and tries to play

Notepad and SimpleText will do the job quite nicely. The metafile
will only contain one line of text. That text is the path to
