A handy trick which works for any situation in which you can't open a file because it's too big for memory (or you just want massive files to load faster to get a sense of what the data's like before you begin analysis in earnest). You can combine -use- with an if or in statement, as in:
use hugefile.dta in 1/50000, clear
or
use hugefile.dta if sex == 1, clear
