Looking for a program to delete duplicate images on your PC, camera or other USB storage devices? Duplicate images can take up a large amount of disk space and increase the cost of backup. What’s more, they could even slow down the indexing speed and the opening of folders if they occupy too much disk cluster. You need to clean unnecessary photos from your disk.
The best and easiest way to remove redundant images is to use a duplicate image finder. But you need to pay close attention when you go to install one on your computer. The browsing and searching efficiency of different programs is quite different. How to choose the best duplicate photo search engine among so many programs?
To make the right decision, you need to know the important steps to choose a good duplicate image finder. Compare and select one for your computer.
Search and comparison technique
Some duplicate finders can only search for files on your disk by name. That is, these types of programs can only find duplicate files that have the same or similar names. That is a great limitation. Most duplicate files don’t always have the same names.
You should choose a duplicate photo finder that can not only search by name, but can also search by file content. Not all programs can search file content and compare byte for byte. Only these programs that use CRC32 or MD5 technologies can do that. To accurately find duplicate image files, you must use the ones that are integrated with both technologies.
Document preview
Most programs can export a simple report after scanning. In the report, you can view information about the files, such as file names, file location, file size, and creation date. And then you can easily separate the necessary files from the duplicates. Although the report provides very detailed information, people can still make a mistake and delete the wrong file.
To allow users to accurately discriminate between original and duplicate files, some programs integrate the Image Preview function that allows users to easily view images without opening them. To avoid deleting the necessary photos, you should choose the duplicate photo finder that supports image preview.
Those mentioned above are the most important measures to consider when selecting a duplicate search tool. You can easily choose the one that has the features.
