Hi folks,
In my ongoing saga to make my own PS -> PDF conversion system I need a bit of help. I know it's possible because there are numerous web based sites offering this service.
What software/script/process would I use to monitor a directory for file additions? When new files are added I then want to feed this file into a script that would perform the PDF conversion and then moved the file to another directory. This is how the existing online systems do it.
I've scoured the web high and low with no success and have asked a few sites for assistance but they don't want to share.

I've found the windows tools but I don't want to use no stinking Windows!! ha ha
Thnaks for any assistance, pointing in the right direction, URL's.
