You might also look into TrueCrypt ( You can create a virtual encrypted disk within a file and mount it as a real disk. And you can do this from a shared drive, memory stick, external HD, etc..

Thanks Austin and Martin.

The question came from our institutional review board who wanted to know whether our analytic data files are passworded.  The example they gave me was Excel and Access, which can password databases. Some of the files where data are stored are shared drives.  I don't think that a single password will prevent access, but at least may deter it.  I couldn't find anything from a Stata search, so I didn't think the capacity existed.

I know there are other ways to deter access (e.g., passwording folders or assigning individual drives which must be logged into).  We'll have to explore these.

But note that zip passwords are not secure.  How secure do you need
the data file to be?  Who needs access?
You might get what you need from openPGP e.g.

Never heard of such a facility. (You can verify integrity via -help

external zip program and add a password to the zip file. Also, dtas shrink
considerably when zipped...

Does Stata have a capacity for passwording data files?
