Method 1

Find duplicate files on Mac manually

The process of finding and removing duplicate photos, documents, music or video files is not that simple and fast when you decide to do it without Duplicate File Finder. Anyway, let’s see how you can find and delete duplicate files on Mac manually.

One of the ways is to sort the files by size using Smart Folders in the Finder.

  1. Open the Finder window.
  2. Go to Apple Menu → File → New Smart Folder.
  3. Click a Plus button in a top right corner and select Search parameters: Kind, Date, Name, File type and others.
  4. Smart folder in Finder to find duplicates

  5. Click “Other …” to find more parameters for searching and sorting files.
  6. For example, if you want to search for and remove duplicate photos, set up the image kind, the file extension (.png, .jpg, .tiff, .gif,  .bmp), the size in pixels and so on.

  7. Such a list will let you take a look at all possible clone files, focusing on the size and the name. Now open each file that has the same name or size and check for duplicates.

Well, as you can see, this helps a little, though not much.

However, if you are not willing to spend a lot of time on this, we recommend using a fast Duplicate File Finder Pro app. Get this app to remove duplicates and organize your files and folders on a Mac in the most convenient way.

Another useful feature of Duplicate File Finder Pro is the Select Duplicates in Folder feature. For example, you can select one Downloads folder and remove all useless duplicates, rather than searching for copies of files in Downloads and various folders.

One more unique feature from our last update is the Merge Folders function, which organizes your folders by duplicates. Duplicate File Finder Pro allows you to reveal all your folders in two lists within one window to review and merge their content. It is very convenient that each new source folder has its own color, so you can easily understand where each source folder’s content belongs.
