Duplicates

Duplicates is a small-sized application made to find and remove duplicate files from the computer to free up HDD space and make room for new items, especially when talking about storage devices with a small capacity. It compares files by their content and displays their full path, size and date of last modification.

Java-based utility with a simple GUI

Since it was made using the Java programming language, it requires this runtime environment to run. However, it's not wrapped in a setup file. Instead, you can copy the downloaded file to a custom directory on the disk or to a removable storage unit and run Duplicates on any PC with Java installed. No new entries are added to the system registry and no new files are generated on the disk.
It's packed in a user-friendly UI made from one window with a neat layout, where you can begin by browsing one or more folders to scan for clone files. Subdirectories are included in the task, while the contents of ZIP archives can be checked optionally.

Find and remove duplicate files

The task's duration depends on the files count. The original files and their duplicate counterparts are grouped together in the results list, where you can examine their full path, size (bytes), date and time of last modification, together with total files and size, and all scanned items. All these details can be printed.
Only selected objects can be deleted. However, this is where Duplicates' functionality ends. Unfortunately, it doesn't implement options for opening a file's location in Windows Explorer or selecting all duplicates with one click while leaving the original objects untouched. File filters would've been practical too, for instance to scan only for files with a particular extension to narrow down the search time when handling large amounts of data.

Evaluation and conclusion

The software utility verified the specified directories rapidly in our tests while remaining low on CPU and RAM consumption. On the other hand, Duplicates doesn't have a resourceful set of options for meticulous users looking for more customization and control over the entire operation.
