Note that you can have Stata -describe- the contents of a file residing on
the hard disk without actually opening it. See the second syntax in -h

Subject: st: Modify large data base without opening it

I'm working with a very large data base (1000m, 2000 vars) and my PC
is taking too long to open it. I would like to know if there is a way
or a specific command to drop some variables without actually opening
the data base.

Thanks in advance,

José Luis Chávez Calva
