DuMP3 : Easily scan for duplicate files of all kinds inside custom folders, fixed, or removable drives, analyze them, and choose which get removed

In depth

A closer look at DuMP3

Working with an abundance of similar files has a high chance of leaving duplicates behind, especially when trying to organize different collections. These don’t really have an impact on your PC’s stability, but you can end up with low disk space. Luckily, there are specialized applications like DuMP3 you can rely on to clean dupes.

Visual design and perks of portability

First of all, you need to check whether or not Java Runtime Environment is on your PC, because it’s a mandatory requirement for functionality. However, the program itself doesn’t need to be installed in order to function, so you can just as well place it on a thumb drive in case you want to use it on other computers.The window you work in is pretty well organized, with different tabs to provide quick access to the location picker, rules, results, and more. Although the name can suggest that the application is dedicated to detecting MP3 file, it can identify nearly any kind of file, not only multimedia, but does perform a more efficient scan on MP3 files based on ID tags.

Select formats to scan and analyze detected items

Scanning isn’t done on the entire computer, and the application allows you to select custom regions. This is done in the first step, and you can include multiple folders, as well as entire drives, be them fixed or removable. A scan is then performed, by the end of which you can select specific formats to filter for the cleanup operation.Duplicate items can be viewed in detail, and this component is especially handy when working with pictures, because visual feedback is provided. The application runs an automated fingerprint scan to tell the difference. You’re then free to remove entire groups of duplicate files at a time.

A few last words

Bottom line is that a clean computer has less chances of running into performance or compatibility issues. DuMP3 is a suitable application to easily find duplicate files of all kinds, analyze them in detail, and decide which still remain, and which get to be removed from your computer.
