That is indeed a large file, are you sure its saved in Stata format as .dta?

Your best bet might be to open it on the computer on which it was
saved (or identical specification with the same version of Stata
installed).

If however its a text file of sorts that you are trying to -insheet-
you could use something like the 'head -n100 [filename] > subset.txt'
command under UNIX-like OS's (which includes the terminals under MAC
OSX) to get the first 100 lines of the file into the file subset.txt.

If you don't have access to such systems you can install Cygwin which
is a UNIX shell for Windows (see http://www.cygwin.com/).  There may
be a similar native command under the DOS prompt but I'm not familiar
with DOS I'm afraid.
