![]() AllDup is a good friend to delete the duplicate files. It allows you to delete all the duplicate files very efficiently. Besides finding the duplicate images and files it also finds the duplicate MP3 of different names. Join_dicts(dups, find_duplicate_hash(dup_list))įor dirName, subdirs, fileList in os. AllDup is a free duplicate file and image finder. Print('Comparing files with the same size.') Print('%s is not a valid path, please verify' % i) Join_dicts(dup_size, find_duplicate_size(i)) The program's default is set to ignore files smaller than 1MB. It has a minimalist GUI, with 4 tabs and a menu bar. # Find the duplicated files and append them to dup_size Duplicate File Finder & Remover simplifies the menial task of finding wasted storage space by locating duplicate files for you, and giving you the option to automatically or manually delete the unwanted ones. Auslogics' Duplicate File Finder lets you search for copies by name, date, size, and contents. Dupe Clear is an open source duplicate file finder for Windows that can help you recover storage space. Takes in an iterable of folders and prints & returns the duplicate files # Adapted to only compute the md5sum of files with the same size It is very efficient because it checks the duplicate based on the file size first. svn paths for instance, which surely will trigger colliding files in find_duplicates.įeedbacks are has a nice solution here. This method is convenient for not parsing. Raise Exception("Unknown checksum method")įile_size = os.stat(current_file_name) Hashes_on_1k = defaultdict(list) # dict of (hash1k, size_in_bytes): Hashes_by_size = defaultdict(list) # dict of size_in_bytes: """Generator that reads a file in chunks of bytes"""ĭef get_hash(filename, first_chunk_only=False, hash=hashlib.sha1):ĭef check_for_duplicates(paths, hash=hashlib.sha1): The software from Big Bang Enterprises is available in two editions. For files with the same hash on the first 1k bytes, calculate the hash on the full contents - files with matching ones are NOT unique. 1 DoubleKiller As evident by the name, DoubleKiller finds and removes duplicate files from your computer. ![]() For files with the same size, create a hash table with the hash of their first 1024 bytes non-colliding elements are unique The solution: Duplicate File Finder will help you locate and remove useless file duplicates to free up disk space and better organize your file collections.Buildup a hash table of the files, where the filesize is the key.Iterating on the solid answers given by and borrowing the idea of to have a fast hash of just the beginning of each file, and calculating the full one only on collisions in the fast hash, here are the steps: Calculating the expensive hash only on files with the same size will save tremendous amount of CPU performance comparisons at the end, here's the explanation. The approaches in the other solutions are very cool, but they forget about an important property of duplicate files - they have the same file size. Fastest algorithm - 100x performance increase compared to the accepted answer (really :)) ![]()
