G'day ObiPanda,

Welcome to the Monastery.

"Glob is not my friend."

Without any examples of your "real subscription folder files", I can't give specific advice; however, here are some suggestions:

• Build up $glob_expression separately and then just call glob($glob_expression). As an example, see my "Re: Set intersection problem" post from a couple of weeks ago, where I had to do something similar.
• The glob() documentation has examples of dealing with filenames containing spaces (which can be considered as a special character). You may be able to do something similar with whatever special characters your filenames contain.
• The File::Glob module may have useful information; in particular, GLOB_LIMIT seems relevant.
• Show us some representative samples of your real data so that we can provide better answers. :-)
