The following review written by one of the Software Informer contributors applies to version 2.1
Duplicate Photo Cleaner is a shareware tool designed to help you with searching for duplicate image files and deleting unwanted copies from your local disk drive.
The program’s design is done in a nice black-and-white style.
The central area of the app is conveniently divided into two halves. The left one displays the original image files, while the right part lists those files that are considered duplicates of the original. The result of a search shows up in a pop-up window at the end of the process. Moreover, you are informed about the estimated amount of time required for scanning. This valuation of the time, that is left till the end of the process, is a useful feature: this way you know whether you can deal with other activities or not. When the search is complete, you have the opportunity to analyze each of the pairs and decide whether to delete one of the files, or leave them as they are.
The Settings window contains some features that may be turned on or off. In addition, you have the ability to set up the similarity threshold value. You can also choose which image file formats to include in the search. Currently, only JPG, PNG, BMP, and GIF files can be selected. However, for such a price the program could have a wider range of supported formats.
To sum up, Duplicate Photo Cleaner easily executes searching through the folders and correctly detects similar image files. I liked working with it, but I would wait for it to be enhanced before buying such a tool.
