How are the files getting dropped into the folder?
If web based perhaps php or perl and have it do its thing upon uploading
the file.

Cronjob the script? 
Use a folder for temp storage and have the script move the file to another
folder at completion. This way the script only has to check if the folder 
is empty instead of running through each file checking the date or indexing 
them.
