If you often find that you create duplicate files as you rename or use files in another context, or just backup more than you had intended, Duplicate File Detectors help you find and/or delete these duplicates and regain the storage space they previously occupied.
Judging from some of the recent comments, it would appear that some cautions should be noted before using this type of software. One might also note that with the cost per gigabyte rapidly decreasing, redundancy is no longer such a bad thing.
What is the duplicate files? There are different degrees of definition. Look at the "Name": the file name must be the same? Look at the "real": the same is a binary bit stream, or to the "content" the same? Most stringent, of course, is to copy a file to another directory, the name is exactly the same content. But in some cases, especially for lossy compression or change the compression ratio, although the binary bit stream is different, but we think they are the same file. For example, two different jpg, file size, but the same picture; 2 mp3, accuracy is slightly different, but the same song; two zip, compression ratio is different, but inside are the same files on different space...... Suppose, we have different solutions. The most rigorous comparison, look at the file name, size, and checksum. Compare by content, you actually have to consider the decoding process, therefore, there will be some more specialized tools, such as re-check found pictures, music, re-check, re-check the video.You should need a true duplicate file finder,which is a good helper for you.
