DuplicateFinder

Keeping your drives free of unnecessary files is perhaps more important now than in recent years, as many users are relying on SSDs that offer very little storage capacity. Duplicates can use up valuable disk space for no reason, so getting rid of them is vital.

DuplicateFinder is an open-source utility that can help you free up space on your PC by finding identical files that are being stored in more than one location. It features a rudimentary design and lacks advanced features, but it can certainly prove useful.

You have a good reason to give this utility a chance if you prefer not to install software on your system unnecessarily, as it consists of a single executable file that can be launched instantly from any location.

DuplicateFinder is also a very small program, so it is very easy to deploy on any PC that needs to be cleaned of duplicate files.

Even though it looks to be a simplistic application, DuplicateFinder provides you with multiple comparison modes. It can identify duplicates based on name, date, length, hash, byte comparison and byte similarity.

When selecting a directory, you can specify whether or not the program should also search in subfolders, and you can use a filter to determine which files should be included in the scan.

Once the application has finished searching for duplicates, you can view them in the right-hand panel, and you can decide which of them should be deleted. However, the program cannot auto-select files for removal, and you also cannot preview them.

It is clear that DuplicateFinder needs more polish, especially as far as the user interface is concerned, but it offers a decent set of features and can certainly help you identify duplicate files. Handling the duplicates is a bit more difficult, but the application is, on the whole, quite intuitive.
