Duplicate Photo Cleaner can find similar image files you keep on your storage devices, thus contributing to a better organization and recovery of a lot of space. The tool has an intuitive interface and you just need to follow the suggested steps. Moreover, the app comes with an excellent user guide that leaves no unanswered questions.
One of the main characteristics of this product is that it supports different types of scan. In Standard mode, which is the most frequently used type, you just pick the desired folder and let the app search for duplicates. There is also the Sector Detail scan, which allows selecting a portion of the source image to find similarities in other picture files. Although it is the most precise, it certainly takes a lot longer. The Same Subject scan, in turn, lets you pick a source image to scan the selected folder in search for other pictures with a similar subject. There is the Folder Comparison mode, in which you select two folders to be compared against each other and is used mainly for folder backup and merge. Finally, there is one mode called Photo Scan, specifically meant to work with the images stored in your photo library.
Unlike other tools, which use mainly file properties as the basis for comparison, Duplicate Photo Cleaner actually 'sees' the visual content to find similarities. Thus, it can find matching photos, even when they are stored in different file formats. Likewise, if you activate grayscale comparison, it disregards color differences and looks for similar patterns only.
The product can be set to your preferences. For instance, you can select the formats you want to include in the comparison. In this regard, a very long list including, but not limited to, such formats as BMP, GIF, JPG, PNG, PCT and SVG. Likewise, you can decide whether you want to include subdirectories. Moreover, you can set a similarity threshold and select the file size range.
When the scan is finished, which may take longer if you demand more accuracy, there are various ways to view the results and make appropriate decisions. For instance, in Multi-Viewer mode, you can compare all the pictures simultaneously. The app also allows making a side-by-side comparison of two images and provides the similarity percentage. Other modes are Multi-Viewer Groups, Table and Tree. Then, you can decide on the actions to perform, including moving the duplicate to another location, replacing it with a link to the original, exporting it to another device and deleting the file. Luckily, you do not need to take actions immediately after the scan, as the application lets you save it for future work.
In short, Duplicate Photo Cleaner is undoubtedly one of the best tools of its kind. It produces accurate results while preserving your work from accidental deletion. There is a trial version, but it lets you manage only ten duplicates.
