Image Comparator

Image Comparator is a small-sized application whose goal is to find and remove duplicate image files, in order to free up space on the hard disk and get rid of unnecessary data.

The tool offers support for JPG, PNG, BMP, GIF, ICO and TIF formats.

It does not require installation, so you can drop the program files anywhere on the hard disk and just click the executable to run.

It is also possible to save Image Comparator to a USB flash drive or similar storage unit, to run it on any machine with minimum effort, as long as it has .NET Framework installed.

An important aspect to take into account is that the Windows registry does not get updated with new entries, and leftover program files are not left behind after removal.

The interface is based on a standard window divided into three areas for viewing images, statistics and logging details, respectively.

All you have to do is pick a target directory and drive, along with the pixels number for comparison, and start the automatic scanning procedure. The lists are filled with with the full path of images and their duplicates (corrupt files are indicated), along with the log details (e.g. total scan time, all duplicates found).

Results can be saved to an MFF file, in case to want to continue the job at a later time. It is also possible to filter file masks before scanning, select the deletion method (send files to Recycle Bin or permanently remove them from the computer), turn the UI language into Turkish, as well as ask Image Comparator to exclude subfolders, double-check results, skip files with different sizes, and automatically delete corrupt items. Options may be restored to their default parameters.

The program carries out a scanning job very quickly, depending on the size of your HDD. It uses moderate CPU and RAM, and includes a help file for inexperienced users. No error dialogs were shown in our tests, and the app did not hang or crash.

Image Comparator comes packed with a handy set of options dedicated to finding and deleting duplicate images. Its only downside is the unattractive interface.
