Not quite sure what you're after?
If you want to exclude numbers, why do you want DT00009999? to be returned?
12:Filter
Mask: ^[A-z]+[\.]*[A-z]*$
RegEx: (enable)
Find names that start with a letter, followed by a letter any number of times, followed by a (dot) zero or more times, followed by a letter zero or more times. That finds only letters & dots.
[A-Z][^0-9], ignores lowercase file names, so /mpthreedir/ is found
[A-z][^0-9], also finds lowercase names, so /mpthreedir/ is not found, but /mp3dir/ is still found
What the above says, is to find a letter, not followed by a number.
In /mp3dir/, m is a letter, followed by p - which is not a number, so it fits the rule (RegEx).
That is different from finding only letters (& a possible dot).
