-contract- and -expand- both change the data in memory. That should have
no effect on any .dta file unless you explicitly -save, replace-.
I don't think it is possible to diagnose what wrong in your case from
the information you give. Perhaps you are looking in the wrong directory
or folder.

I tried the command contract, wasn't succesfull with expand, than
closed Stata completely and assumed that I can open my original
dta-file agan. However, there wa sonly a version of yesterday. All my
changes of today's session which I saved several times , where gone.
What happened, and how can I get the toadys data-file.?
