Comparing Size of files?

Dear Sirs,
a programmer friend of mine pointed me to Hazel, sayin' that probably it is able to solve my problem, but reading on the website
I need to monitor a folder (the automatic backup folder of my DAW program).
Every time a file is added I need to compare its size to the one before and if its size is smaller of at least 200 KB, i need a notification (there's a horrible bug going on, corrupting the sessions and the backup sessions, but you get to know it only when you close the opened session and reopen it, and the only indication is that the backup sessions -taken every 5 minutes- decrease in size of a certain amount of KB).
Is it possible to do that with Hazel?
thanks
Raffaele
