Uniqueoid

Duplicate files might end up taking a significant amount of storage space you would otherwise use to store other data. That is why a periodical duplicate cleaning session is recommended. To do so, a dedicated application is required, as carrying out the task manually is tedious. Created in Java, Uniqueoid provides a cross-platform software utility that can serve to this purpose.

Uniqueoid requires no installation, but the Java JRE package must already be installed on your computer as a mandatory prerequisite. The application can process a combination of folders and individual files, as added by you when starting a new search.

Uniqueoid parses the chosen folders recursively, meaning it also takes a look into sub-folders, at each and every file. In other words, it compares a file with all the others, trying to detect all the duplicate data. The comparison is based on the hash codes of all the files, with MD5, SHA-1, and SHA-256 being supported.

Once the scan is completed, Uniqueoid displays a list of all the groups of duplicate files in the Results section, along with their hash codes. As expected, it also features a preview area for graphic files so images can be compared side-to-side. On the other hand, no preview options are available for other types of files. For instance, it would come in handy to have a built-in audio player to load a small section of duplicate songs or an integrated mini-browser for HTML files.

You can use Uniqueoid to eliminate copies of files you don't need, either by selecting them manually or by using a template to mark your choices. Files are immediately removed from your computer, so Uniqueoid manages to free up storage space.

Uniqueoid provides a quick and easy means of getting rid of duplicate files on a computer, but it has a bit more to go before matching its competition in this field. For instance, it cannot compare files based on other criteria, such as elements in a photo or the content of a text file.
