Key Takeaway

File names are generally not important in identifying duplicate files. With Cisdem Duplicate Finder, which compares file contents and ignores file names, you can accurately find duplicate files that have different names on your Windows PC, Mac, iPhone, or Android device.

In many cases, duplicate files are unnecessary. You don’t need two copies of the same photo of your cat, unless you are keeping the extra one as a backup.

When organizing your files, if you spot two files sharing the same name, you can take a closer look and delete any identified duplicate. But what about duplicate files with different names? These can be harder to find.

In this article, I’ll show you how to easily, quickly and safely find and remove duplicate files on your device, even if they are differently named.

 

Steps: How to easily find duplicate files with different names

Using software Cisdem Duplicate Finder is the easiest way to handle those duplicates. Below you can find the instructions for different devices.

On Windows or Mac

Step 1. Install Cisdem Duplicate Finder.

Download and install the tool on your computer. Open it.

Free Download Windows 10 or later Free Download macOS 10.11 or later

Step 2. Add the location(s) to scan for duplicate files.

To find duplicate files in a folder or drive, add location using drag and drop or the Add button. (The Add button is recommended on Mac.) To find duplicate files within and across multiple locations, add these locations.

To scan a location on an external hard drive or in a cloud storage service, please first connect the external drive to your computer or install and set up the service’s desktop app.

Step 3. Start the scan.

Click the Scan button, and Cisdem Duplicate Finder will start comparing files by their contents and identifying those with exactly identical content as duplicates.

Optionally, you can go to Settings for customization before scanning.

Step 4. View detected duplicate files.

When the scan is complete, the results window will appear, displaying all found duplicate files. You can conveniently view, sort and search them.

Step 5. Select duplicates for removal.

In each set of duplicate files, the tool has automatically selected all but one file for removal. You can manually adjust the selection if needed.

In addition, there are preset rules for mass selections. On the left side of the results window, highlight the sets to which you want to apply a rule. Next, choose a preferred rule. For example, choosing the Select Newest rule will select all but the oldest file for deletion in each set.

Step 6. Delete all duplicates at once.

Click the Delete button to remove all the selected duplicate files. Confirm the deletion.

By default, the deleted files will go to the Recycle Bin (on Windows) or Trash (on Mac). And this allows easy restoring of files when needed.

 

On Android or iOS

Step 1. Get the app.

Install the duplicate file finder on your Android device, iPhone, or iPad from the app store.

Note

Cisdem Duplicate Finder on iPhone or iPad supports finding duplicates in the Photos app only.

Step 2. Start a scan.

Tap Start Scan, and the app will start scanning files across your phone or just the Photos app (depending on your device) and comparing their contents to detect identical files.

Step 3. View scan results.

When the scan is done, you will see a list of detected duplicates. You can view their information and preview them using the associated apps.

Step 4. Remove duplicates.

With automatic selections and manual adjustments, you can easily make sure that unwanted duplicates are selected for elimination. Then, tap Clean at the top of the screen to delete selected files.

 

Does the name matter in identifying duplicate files?

What are duplicate files?

A set of duplicate files is two or more files that are exactly identical, regardless of their file names (or simply names). They can share the same name or have different names.

Identify duplicates manually

When you look for duplicate files yourself, I tell you that the name can be helpful. For example, when you see two files that have the name that is called “IMG_0050.jpg” and “IMG_0050 copy.jpg”, you can know from the name that they may be duplicates. But, be careful. If they have completely different names, you are not noticing them.

Identify duplicates automatically

When duplicate file finder software uses algorithms to automatically detect duplicate files, the names don’t matter.

For example, Cisdem Duplicate Finder focuses on comparing hash values of files. Each file has a unique hash value that represents its content. This is just like each person has a unique fingerprint. File names don’t affect hash values. This tool also compares files sizes and types to further ensure accuracy.

Summary

Names can help you spot potential duplicate files in manual identification, but software tools don’t consider names.

 

Conclusion

Duplicate files! They can pile up as time goes by. They use your storage and they are a mess. It can be good that you clean them up often. But, finding duplicates can be an easy thing to do (especially when they are different in names). It's good that dedicated software can make it easy to identify and remove duplicate files (regardless of their names). And using such tools help you have a clutter-free and organized computer.

    One thing I wish the article covered more is how to handle duplicates in cloud storage(Google Drive, Dropbox). Sometimes these services sync unexpectedly and create duplicates.
