Similarity is a software tool that helps people get rid of the clutter from their hard drives, by scanning their computer for duplicate items and removing them.

The installation process does not offer to download or add third-party products, and runs smooth. After you complete it, you are greeted by a straightforward interface which can be used by anybody, even people with little to no previous experience with computers.

It is comprised of a menu bar, a few shortcut buttons and a tabbed panel, so that you can quickly browse through all the options available. The first tab enables you to view the entire contents of your hard drive as a list, and as a tree view. From here, you can select the folder or partition to scan.

Once you have done this, you can easily scan the computer for image or track duplicates, or analyze audio files. Both these processes are quite friendly to your system’s resources and therefore, you can run this utility alongside others without problems.

On the one hand, the analysis enables you to view information regarding songs and videos, such as rating, sample rate, size, bit rate, duration, clipping, silence, maximum frequency and spectrum.

On the other hand the duplicates scan lets you view all files that have similar content, and groups them, so that you can identify them faster. Selected audios can be played, their ID3 tags can be tweaked, and you can also view the spectrum or sonogram analysis, while photos can be opened in your default image browser or in Windows Explorer. Both types of files can be marked, moved to a custom location, or deleted from the hard drive.

Taking all of this into consideration, we can safely say Similarity is a useful piece of software, with plenty of options to help you manage the duplicate contents of your hard drive. It has a good response time and an easy-to-use interface.
