How To Find Duplicate Files ?

Step-by-step instructions

• Select the drives or folders that will be scanned.
• Set filters to include or exclude folders, files or file types.
• Select the scan method: exact duplicate files, similar files, duplicate and similar file names, equal file sizes.
• Hit the "Scan" button. This may take some time on large volumes.
• Use auto-check to select the duplicates automatically based on size, name, quality or other properties.
• Review the results.
• Delete, move or copy the duplicates.

A duplicate finder scans all the designated locations for files and compares their content. Many duplicate finders on the market use checksums like CRC or MD5 to compare files as it is faster. While this improves performance it often produces incorrect results and may list completely different files as duplicates.

Best algorithm for scanning duplicate files is byte-to-byte comparison. This means that every byte from the file is compared with the corresponding byte from the other. While byte-to-byte comparison produces 100 % accurate results it is the slowest of all scan methods.

Our duplicate finder uses an optimized version of the byte-to-byte comparison which provides extremely fast duplicate scan while guaranteeing that the files are 100% equal. Every optimization or modification to our algorithms is thoroughly tested. Our tools will never list false positives - incorrect results.

P.S. Duplicate files are also known as repeated, dupe, same, double files, identical or file copy/copies and considered as unnecessary, unwanted, unused, redundant and junk files useless for purpose. The process of removing duplicates is called deduplicate, dedupe, deduplication. Clone remover will easily help you find and delete duplicate files.
