Compare File Contents, 100% Accurate Result

Compare whether files are the same at the binary level, that is, compare file contents. Since only the file contents are compared, the truly duplicate files must be found, regardless of whether the file names and modification times are consistent, even the extensions are inconsistent (considering the case of deliberately modifying the extensions for safety), they can be found out also.


Built-in High-speed Comparison Algorithm

This product uses our original “file binary virtual crosspoint intelligent memory” algorithm to quickly obtain the hash value of all files in the scan source, and then uses the fast hash reverse sorting technology to obtain a list of duplicate files at one time. These repeatedly tested and optimized internal algorithms make our product to be much faster than most other similar software under the premise of ensuring the accuracy of the results.

CheckSmart Selection and Other Multiple Checking Methods

Except to quickly, comprehensively and accurately find duplicate files, another important function of our product is to quickly and accurately delete unwanted ones. To this end, we investigated and analyzed a large number of actual user behaviors and the reasons for repeated files, innovatively developed the powerful automation function – “smart selection”. In addition to smart selection, our product also provides other 5 check methods, e.g. by paths, by drives, etc. 

One-click to Get Result

Very Easy to Use, Only Need 1 Click to Get Result

For normal users, do not need to adjust the scanning conditions and options, we have set the default settings according to the most common application scenarios. After the software is launched, directly click the “Find now” button to get the list of duplicate files as you want.

Scanning Conditions

Flexible Scanning Conditions: Drives, Folders, Files, Sizes and Types

You can specify the drives, folders and / or files to scan at the “Select resources” area on the left. Specify the file sizes to scan at the “Select size(s)” area on the left, and the files outside the specified range will be ignored. Specify the file types to scan at the “Select type(s)” area on the right. You can also specify excluded directories on the “Options” interface. 

Reusable ResultReusable Result: Save / Load the Duplicate Files Listing

When there are many duplicate files, and you need to carefully review the results and then check and delete those that are not needed, it may be impossible to process all the results due to time reasons, such as shutting down PC after get off work or bedtime. At this time, it is very useful to save the repeated list so that it can be processed next time when your PC is turned on. Just click the “Save” button (disk icon) on the result interface to save result, and click the “Load” button (down arrow icon) on the main/result interface when you need.

Helpful OptionsHelpful Options: Smart Selection, Comparing Algorithm, Sub Folders, etc.

We provide a number of practical options to help you use this product better and faster, such as smart selection, comparison algorithm for large files, play a sound after scanning, scan all sub folders for a specified path, do NOT scan the system/hidden files anyway, do NOT scan the listed system / special folders, etc.
