How can I find duplicate files on my Mac? Duplicate files, especially those with large size, can eat up a lot of storage on a Mac computer. The problem with duplicates is that you don't know when you downloaded multiple copies and over what time frame. That makes them harder to find the duplicates. You can delete them manually, of course, but that would be a labor-intensive task. You can also find and delete them using command line executions on Terminal. Finally, you can search for a good utility that will take care of the problem for you, not just once but on a regular basis.
Before we describe the three methods, keep in mind that finding duplicate files is a tricky thing because of different file names, different versions of the same file, different download times and so many more variables. The first method shown below will make your manual search a little easier and a little more fruitful.
