The .sit at the end of the filename means that it is a "StuffIt" file.
Stuffit is used to compress files for UL and DL.  To convert it, you
need the program, which can be found on most all mac boards (it also
includes a BinHex4.0 function).  However, your description of the file
makes it sound like it should be a .pit file (PackIt) another type of
compressions program (StuffIt will Un-Pack files).  If it says .sit,
yet appears as a generic document, the file may have been corrupted
during transfer, so you may want to check into this possibility as
well.  Hope this helps.
Geoff.
