Find and Remove Duplicate Files in Dropbox Using the Website

Since the Dropbox app is basically used to share files, it has limited options in searching for duplicates. In general, duplicates are files that have the same name, size, type, and binary data. Occasionally users rename a copy of a file for different reasons, so duplicate files may have different names. However, even when two files have the same title, it does not mean that they are duplicates.

If you want to find duplicate files using the Dropbox website, take the following steps:

1. Log in to your Dropbox account.
2. Select My Files. At the top of the list of your items, you can see several criteria that you can use to sort your files. As we mentioned earlier, duplicate files have identical size and extension, so choose these criteria to find useless copies in Dropbox.

   

3. By default, your files are arranged by name in alphabetic order, so you can try to detect duplicates by their title, size, and type. If you keep files in folders, you should open each folder, sort items and then, find duplicates. Once you have detected some files with the same size and extension, check them for identical content. If they are just copies, select the unneeded files and click on Delete in the menu on the right.
   

You can also mouse over the useless copy and click on the ellipsis next to it. Then, select Delete from the pop-up menu.

Unfortunately, this method is time-consuming and you may misunderstand different files for the same. Even if the name, size, and type of files are the same, this does not guarantee that they are duplicates and have absolutely identical data. Dropbox has an inaccuracy, as it rounds the value of a file, making two files seem identical even while the file size may differ just by one byte.

Find duplicate files in Dropbox using Finder’s Smart Folder

If you use the Dropbox desktop app on your Mac, try to find duplicates via the smart search in Finder. For this, complete the following steps:

1. Open Finder → in the sidebar, select Dropbox.
2. In the menu bar, click File and select New Smart Folder from the pop-up menu.
3. In the right corner under the search line, click Add (+) → in the field that appears, choose Kind in the left field and Document in the right field to sort items.
   
4. Select “Dropbox” to view all your Dropbox files.
   
5. This Finder search option allows you to sort items by name and kind among all your Dropbox files. You can also change the search criteria to Image, Movie, Music, PDF, or Text to narrow your search query.

   For instance, if you want to delete duplicate photos in Dropbox, you should change the search criteria. To find duplicate files in Dropbox, within the Finder’s Smart Folder, change Document to Image → select the extension type (JPEG, PNG, GIF, etc.) → click Plus to enter additional criteria → select File Size, less or more than, and set the number of kilobytes.

   
   You can change the search criteria to find duplicate files depending on your content.To delete duplicate photos or other files in Dropbox, right-click on the unneeded replica and select Move to Trash from the pop-up menu.
   

Pros of this method are that you do not have to individually open each Dropbox folder, as you can see all your files at once. Cons of this method are the same as for the previous method. Moreover, the searching criteria are limited, and they are not universal for all types of files. You should set various search filters depending on the type of file, which takes time and makes it quite complicated to find duplicate files and folders in Dropbox.
