How to ignore strings that don't match a certian format?

I am getting an array of strings based on all the files in a directory.

If I am only concerned with strings of the format #####XXXX######-###.jpg, how can I get it to ignore ones that do not fit the format? I am concerned that If "bad" ones get in, it could cause problems when I am trying to do operations with them.

ex: I would want a file called 16800EBHR052708-001.JPG, but would not want records.doc, DMC1234.Jpg, etc...

so If I have Pics() As String what can I do to it to remove unwanted entries?
