The file selection dialog sorts alphabetically.
There is no quick-n-easy way to resort the data groups once in
Athena. The best solution would be to name the files in a way that
alphabetical sorting will be the same as time sorting. The way to do
that will be to name the first file "f01.fio" rather than "r1.fio".

That is a well known, well discussed problem. Ifeffit is written in
fortran. Fortran does not have dynamic memory allocation. The only
practical solution is tonot read so many data files in at a time.
I wish it were different, but it's not.
