there is no way to get append to recognize a wild card. However, you can use the "dir" extended function. Type

help extended_fcn

example:
local x :  dir "c:\mydir" "*.dta"
foreach d of local x {
cap append using appendfilename
save appendfilename, replace
}

Greetings!

I am wondering if there's a straightforward way to append a large
number of .dta files into one file using Stata? The -append- command
seems to disallow wildcards in the file names.  I do find one method
from UCLA's ATS website,

http://www.ats.ucla.edu/stat/stata/faq/append_many_files.htm

but I'm still hoping there's an easier way, or somehow getting the
-append- command to recognize the wildcards - so that I could just
simply type

append using *.dta

Thanks :)
