Verdict

Wise Duplicate Finder is user-friendly and can help average users easily remove duplicate files from their PCs. However, you may need a more powerful tool if you are looking for more advanced features, such as support for cloud storage and duplicate selections by folder.

 

Is Wise Duplicate Finder free to use?

Yes, it's free to use.

 

What is the difference between Wise Duplicate Finder Free and Pro?

The free version automatically finds duplicate files and displays them for you to view. However, you need to upgrade to the paid version to use the feature that automatically selects duplicates for one-click deletion.

The paid version costs $19.95 per year. There isn't an option for one-time purchase.

 

Is Wise Duplicate Finder safe to use?

Yes. It is safe to download, without any viruses, bundled software, or adware. But make sure that you download it from its official website. It's also safe to use due to the back up feature and deletion confirmation message to prevent accidental deletions.

 

Wise Duplicate Finder main features

3 compare modes

Wise duplicate finder has three compare modes for you to choose, which are "Match Name and Size ", "Partial Match" and "Exact Match".

Match Name and Size: In this mode, Wise Duplicate Finder will compare the duplicates based on file name and size, regardless of the file content. This means that, even if the file content is different, as long as the file name & size is the same, the mode will treat them as duplicate files.

Partial Match: Wise Duplicate Finder match part contents of the file with this mode, and match MD5. This means it’ll not only consider whether the filenames and sizes are the same, but also compare part file contents. Search speed will be slower with the Partial Match mode.

Exact Match: In this mode, Wise Duplicate Finder will compare the file contents to see if they are duplicates, and neither the file name nor the file size will affect the comparison result. The scan results of the Exact Match mode are more accurate than other modes, but its scanning speed is the slowest. I tested these 3 modes, it only took a few seconds to scan my entire C drive in Match Name and Size mode. However, in Exact Match mode, it took nearly 5 minutes.

File size filter and exclusion list

Wise Duplicate Finder offers file size filter feature. It allows users set the minimum and maximum size range of files to scan. For example, you can choose to only search for duplicate files larger than 10 MB and smaller than 1 GB. Also, the Exclusion button (under the Options tab) can let you you exclude some files or folders from search results. And this prevents some important files on your computer from being deleted maybe.

All file types

The File type menu on the tool bar lets you sort the found duplicates by file types. You can also filter the file types before scanning. There’re 10 options for you: Audio files, Compressed files, Graphic files, Help files, Internet files, Mail files, Official files, Temporary files, Text files and Video files.

Preview pane

The preview pane can be opened or hidden from the right column. Compared with other duplicate finders, the preview function of Wise Duplicate Finder is not very well. I prefer those duplicate finders that allow me to compare duplicates side by side. The preview pane is also a bit small and cannot be zoomed in for viewing. What’s more, not all types of files can be previewed.

Keep one

If you don’t have too many duplicate files on computer, you can manually select duplicates to delete after viewing. This also ensures that the deleted files are the ones you don't need. The Keep one feature is available for pro users and can help you select all copies in batches except only one. And there’re 4 options: keep the oldest, newest created, oldest modified or newest modified.

Backup and restore

Wise Duplicate Finder provides 2 methods to protect user’s data. You can choose to delete files to Recycle Bin. That way, you can easily get back the important file from Windows Recycle Bin if accidentally delete it. It also supports backing up files before permanently deleting. But the backup process will be long if you removed too many duplicates.
