Setting Up the Search for Duplicates
Once you have downloaded the program, it’s time to look for duplicates on your Mac. To do so, launch Tidy Up!
You will be presented with a screen like this:
On the left you have all the possible sources where the program will perform its search, while on the right you have all the kinds of files you can search. It’s worth to note that with Tidy Up! you will be able to look for a variety of duplicates and not just photos. Anyway, for purpose of this guide we are going to focus on images.
Click on the arrow on the left of the first label Images and then, select “All Kinds" under the Duplicate panel.
As said by the program, selecting this option will start a search for all images that are exactly the same, even if they have a different name. You can of course also use the second option: “Similar."
What I’ve found during my tests is that with this second option the program will be a little less precise, providing you with pictures that are different from each other but they are listed anyway because of the presence of an identical particular.
After this choice, select on the left where you want the program to look for duplicates. Identify the local disk where you have your iPhoto library.
In the Trial version you are only allowed to do a basic search, therefore you can’t search just a specific program. This option will be available after you purchase a full license.
