Search and Comparison Technique
Some duplicate finders can only search files on your disk by name. That is, such kinds of program can only find duplicate files which have the same or similar names. That is a great limitation. Most duplicate files do not always have the same names.
You should choose a duplicate photo finder that not only can search by name but also can search by file content. Not every program can search file content and compare byte by byte. Only these programs that use CRC32 or MD5 technologies are able to do that. To accurately find the duplicate image files, you need to use the ones that are embedded with the two technologies.
File Preview
Most of the programs can export a plain report after scan. In the report, you can view the information of the files, such as file names, file locations, file sizes and created date. And then you can easily separate the needed files from the duplicates. Although the report provides very detailed information, people may still make a mistake and delete a wrong file.
To enable users accurately discriminate between original files and duplicates, some programs integrate Image Preview function which allows users to easily view images without opening them. To avoid removal of needed photos, you should choose the duplicate photo finder that support Image preview.
The above-listed are the most important measures you should note when you are selecting one duplicate search tool. You can easily pick and choose the one which has the features.
