Hazel does not check continuously!!

Hi all,
I am a new user of Hazel and Mac actually. I have made a rule to copy all jpg files from one folder to another and set "if file exist" option to "replace".
Then,
when I modify one of the jpg files in the source folder, Hazel does not replace the modified jpg file with the existing one automatically. When I trigger from "run rules" it replace he figures.
I wonder if I am doing something wrong. If I add a new figure to the folder, it automatically copies that to the destination folder but doesn't replace the modified ones.
Thanks for an answer!

What is the condition you set for the rule to fire?

Hi,

I have two rules:

1. Go into subfolders (downloaded from the website)

2. The second condition is to look at the files based on their extension as jpg

then

copy file to ... folder

in the options, "do not copy if a dublicate" is not selected,

and

if file exists "replace" is chosen.

When a new file is added to the source folder or its subfolders, the rules are running. However, it doesn't do anything if a file is modified (therefore a new file for me).
When I trigger the rules manualy, it works perfectly and changes the modified pics.

You should add a condition like "Date last modified is after date last matched". Normally, Hazel won't continuously run rule's actions over and over again if the conditions haven't changed. By adding the above, you make it such that the conditions will re-trigger when the file is modified. Give that a shot and report back.
