dir does not support single-character wildcards.
You could remove the superfluous filenames afterwards, e.g.:
>> S = dir('aaa*.txt');
>> S.name
ans = aaa.txt
ans = aaa0.txt
ans = aaa1.txt
>> C = {S.name};
>> X = cellfun('isempty',regexp(C,'^aaa\d.txt$'));
>> S = S(~X);
>> S.name
ans = aaa0.txt
ans = aaa1.txt

Yes - Same Operating system. What is the wild character for specifying one character?
Thank you,

The Mathworks documentation says that wildcards for single characters is not supported.
