How can I filter a specified File Type.

icezero has asked for the wisdom of the Perl Monks concerning the following question:

I need to filter a Filetype. the specification of that files are the date.

 
For Ex. file a) XXX11072002XXX
             b) XXX01012002XXX
[download]

So, i only want to filter the files from the 11.7 th date.
