...It helps you to discover the status of each file in both directories: if it's only in one of them, if it's newer in one than in the other, or if they are simply equal. It also support file content comparison using a hash function, although it's very time consuming. After letting you to choose which files do you want to synchronize, it performs the right operations to make both directories equal (or not, if you want it different). The program can create a backup of the files before overwriting them.

Manifest Maker is a graphical Python application which takes a file or group of files and creates a plain text manifest list of each item. The manifest includes the file name (including directory structure) as well as a checksum of the file. (No longer maintained)

Filecalibur calculates hashes of the analyzed files (using hashdeep) and stores them in text files. Using this hash files, differences or modifications of files within this collections are identified and used to modify other collections. It uses rsync to synchronize filecollections with each other. In the end Filecalibur does nothing what you would not be able to do by hand - but here you can keep track of several tousand files. If you do backups, Filcalibur ensures you that your backups are really identical.

...Algorithm is simple and suitable for large file sets with few differences: basic set of duplicate candidates is determined by file size, then candidates are compared byte-wise. So for files which don't start to differ by growing at the tail it reduces read operations greatly compared to hash-based comparision (i.e. test case: 40GB of files, 16GB RAM, many differences: initial compare (uncached by OS) around 300sec, subsequent compare (relevant file parts cached by OS) ca. 2sec) Note: this program is not related to lsdup

A program to calculate and verify checksums of multiple files with wizard-like GUI. Supports 12 hashes: CRC32, MD2, MD4, MD5, SHA1, SHA2, RIPEMD,Whirlpool, ED2K, AICH, Tiger, TTH. Allows processing of nested directories and updating of checksum files

DuMP3 is a duplicate and similar file finder. It finds exact duplicate binaries by hash, similar text files by substring content, images (JPG, BMP, GIF, PNG, etc) by color and audio files (MP3, WAV, OGG, etc) by wave data. Future: fonts, video.

fafisu is short name for "fast file hash". it determines an md5-checksum from a 4 KB part of the middle of the file (you can change the size of that part). it is enough to use this checksum for determine if files could be equal. than use md5sum

md5cache is best described as an fast, improved "md5sum". it determines the md5-hash of a file and print it out. but, on a second call to the same file, as long as it keeps unchanged, there is no need to rescan the whole file again. its database driven
