string fns;
string path$ = System.path.program$ + "Samples\Import and Export"; 
findfiles fname:=fns$ ext:="S*" recursive:=0;
fns$=;

==> It output only one file “Chinook.sqlite” and the file name is not start with “S”.
The correct result should be 4 files, includes S15-125-03.dat, S21-235-07.dat, S32-014-04.dat, stars.mdb.

Fixed in Origin 2026b.
