After selecting all the duplicate files, click on the gear icon and select “Remove Marked from Results.”

The next option we have is Delta, and it does not seem to be very useful, but if you are thinking of scanning the whole drive like C drive, D drive, or external hard drive, then it can be handy to know which folder file you are deleting.

3. Duplicate Manager Lite.

The duplicate manager is one of the best free duplicate file finder app. There is a duplicated manger pro as well; however, we got our hand on free Duplicate Manager software.

Duplicate Manger software

It an easy to use software as it can scan and clean more than 1 million files within six minutes.

If you are looking to scan your hard drive, then it’s per-installed in the software.

Scan mac hard drive pre installed option of duplicate manger lite software

It makes it easy for you to scan your PC Hard drive as it’s one click away to scan and delete the duplicate files.

You get three main options when you open the software: Remove duplicatesAuto Select, and Scanning.

three option of software

a) Remove Duplicates.

In remove Duplicates, you get two options move deleted duplicates to Trash and Create an alias in the place of removed duplicates.

remove duplicates

If you keep the first option check, then all the duplicate files go into your Mac PC trash folder.

The second option you have is create an alias and I don’t think it’s very useful neither I really want to test it…Hahaha.

b) Auto select.

Now the next we have is the auto select.

Auto Select options

Set on what basis the application will choose the original.

It will be the newest file, or it will be the oldest file or will choose the original file by Folder priority.

We recommend using this mode when you scan multiple folders. You should set the folder priority before starting the scan.

Also, you can define to keep one original for all folders or each scan folders.

Exclude list for Auto Select option lets you exclude folder to be selected when you are deleting duplicate files.

c) Scanning.

Scanning

To Speed up the Scan process, set the minimum file size to scan at the same as 200 KB.

Exclude List for Scan, let you exclude the file or folder.

Scan package type as file, determine which packages will be scanned as a folder.

Comparison Mode helps to search the identical files—the Files which hold the same content.

By using the comparison Mode, you can search a file with the same names & modification date or all the files greater than the selected size.

Now, As we know about all the settings, we should have to add a folder or drive to be scanned.

You have two sections here on the left side and the main one.

Left Side Section: Click on the add button if you want to add the drive to be scanned thoroughly.

Left side of the software

Main Section: Click on the add button if you want to add a selective folder to be scanned thoroughly.

Now, as we have added the folder or drive, click on the scan.

The scan shows you the result page.

Duplicate manager result page

On the top section of the software, you get All files, images, video, music, documents, apps, archives, and others.

After the scan, all the related files show up in their sections as per the file format.

If you want to view the file, then select the file and click on the eye icon.

If you want to delete all the copied files, then click on Auto Select[Data] and click on Remove Selected.

select the file and remove selected

d) The Con of the software.

It does not allow you to delete all duplicates files at once. It’s good software; however, it’s not as good as the DupeGuru.

If you thing showing advertisement instead of asking money to buy the pro version is okay with you, then do let us know in the comment section and do share this post with your friends so that they can share their valuable opinion.

4. Duplicates Finder.

Duplicate finder

Duplicate Finder is another easy to use application, but the problem is the same. You can not delete all duplicate files at once.

However, there is no pro version of this application to select all duplicate files, but I hope developer will add this option.

Now let talk about how you can use duplicate finder software.

It’s very easy to use application as you just need to click on the plus icon – Drag folders or Browser, and you can add the folder to be scanned.

Add or browser folder

Once you add the folder, click on “Find Duplicates Now” Button, and it starts the scan.

Folder add to the scan

After adding the folders, you get the gear icon/ configure option to customize your scan.

These options let you narrow down the search results. Selecting search file types to improve scan performance.

Change the duplicate finder configuration

In select files type, you get two options: Search for all file types and Search for these file types only.

You can select the options as per your requirement and click “Next.”

When you click Next, you get the screen to customize the file size range. It’s like ignoring the files smaller than your selected size and larger than your selected file size.

Customize the scan for smaller file larger file and date modification

And you can set a date if you do not want the latest file, oldest file, or newest file to be scanned.

After customizing the options, click Next, and you get the option to customize a particular file(or group of files) to be searched.

Customize the particular file search

After setting up the software as per your requirement, click on “Find Duplicates Now” Button. You get the result page, select the file, and click on “Remove Selected.”

5Duplicate File Finder

Duplicate file finder is another easy to use software.

When we were testing this software, we tested four times, and we did not see any problem using this software.

Even it deleted the files without asking to upgrade the application to a pro version.

You might see a problem in deleting the duplicate files if your drive has a lot of duplicates files.

Eventually, we are not sure about it, but we think you might get a problem when you delete a large number of duplicate files.

Now let’s talk about the software. What are the options you get when you use the software?

  • Click on the plus icon, or you can drag to add the folder or drive to scan.

Disk xray lite

Disk Xray lite is another duplicate file finder software. You can use it for free if your files are less than 500 MB.

It offers free duplicate file cleaning if your folder does not contain files of more than 500 MB. Eventually, it can be done if you are looking to delete duplicate photos.

When you install and open the software, you get the screen give in the picture below.

Click on “Start,” and it opens up the software screen to use it.

7. Dolly Lite: The Duplicate Finder.

Dolly Lite

The Dolly Lite is another easy to use software to delete duplicate files, but the free options allow you to remove 20 groups of files only.

If you want to delete more files than 20 files, then you have to buy it, or else you create a new folder. Copy the 40 files and past it to the new folder and scan it.

20 Groups mean 20 original and 20 duplicate files.

Now let’s talk about how to use it.

Click on Plus icon, Drop, or Add Folders.

Now you get a drop-down option to add the folder or drive.

I suggest not to add any drive in the software. Instead of that, add a new folder, as I suggested before.

Once you add the drive or folder, it starts the scan within a minute. After completing the scan, it shows you the duplicate file given in the picture below.

Click on smart select and clean to remove all the files.
