![]() ![]() This compare type can be helpful when you are searching for undesired copies (e.g. Select this option to find all files with equal file names. This is helpful in case files had been moved from one location to another, which might modify this time stamp. Select this option to identify duplicate files by looking for equal names and sizes.Įqual to the very first compare criteria, but without regarding the "last modified" time stamp of the files. ![]() This is much faster than using check sums to indicate duplicates, but it is also less accurate. Select this option to identify duplicate files by looking for equal names, sizes and last change dates. However, the SHA256 algorithm is significantly slower than MD5. While it is very unlikely that the MD5 hash algorithm produces the same hash value for different files, the SHA256 algorithm further reduces the statistical risk of such hash collisions. This search option works like the MD5 checksum mechanism, but uses the SHA256 algorithm instead of MD5. This is more accurate then comparing files by their name, size and date but it is also much slower. Files with the same content will have the same hash value, files with different content will almost certainly have different values.Įmpty files are ignored, since there is no content to compare. When using MD5 checksums, a so called hash value is calculated based on the contents of each file. ![]()
