Or you could just use the emptyok option with save:
save filename, emptyok
which will save the file even without any observations.
Then append away.

Subject: st: Re: Appending several files
A simple technique can be useful to "trick" Stata to behave like a
dataset exists:
* create an empty dataset with one observation and one variable:
set obs 1
gen articifialvar = 1
* now you can do anything where Stata expects an open data set to be
present, e.g. from
* the current discussion:
qui fs *
foreach f in `r(files)' {
append using `f'
}
* following appending all the files the first imaginary observation
and variable can be dropped:
drop artificialvar
drop in 1
