I agree with you about config files, I think they would be useful, but for right now you can simulate searching for things like this. Obviously, config files allow you to do some cool things, I just wanted to be sure I understood what you meant!
Regular expressions are similar to wildcards. Currently, you can use "*" to mean any number of characters in a filename. In my example above, *Gomez*.mp3 will find any mp3 with the word Gomez in the filename. *.mp3 would find ALL mp3 files. Regular expressions allow you to go farther than just * or ? (single character) and allow you to specify a number or group of numbers, one, two, or three characters etc. Basically just a more feature rich implementation of wildcards. however, with the power regular expressions bring, they also bring a fair amount of complexity. For a decent explanation (and a look at how complex things can get) go to
http://www.bulkrenam...ms/viewtopic.php?t=5. The cool thing about regular expressions is you can use them... or not! Power users can keep their search broad while narrowing it (paradoxical?). Novices can play around a little, and complete newbies can avoid them altogether. I personally do not know how to use them, mainly because not many programs support them. However, if FindRun goes the way of the minibrowser, people will eventually begin looking for more than one match (the current intention of FindRun)to a particular search. You, for example, may be looking for an entire album of mp3's from Miss Miranda, or all files that match this expression [a-e][ ](Mid)*.rtf, which would match all rich text files about "A Midsummer's Night Dream (I think, as I said, I am a novice to regular expressions... but I would like to learn!).
As I said, regular expressions are complex and I dont know how easy it would be to implement. I've only used them to batch rename files (that's how I found the link above) and while I dont use them often even then, they are EXTREMELY handy in the correct circumstances. Those are my thoughts, have fun
