    dupeGuru

    dupeGuru

    Find duplicate files

    dupeGuru is a cross-platform GUI application written in Python (with Qt/Cocoa UI) that quickly detects duplicate files on your computer using flexible scanning modes—including filename fuzzy matching, content comparison, and specialized Music/Picture modes. On some linux systems pyrcc5 is not put on the path when installing python3-pyqt5, this will cause some issues with the resource files (and icons). These systems should have a respective pyqt5-dev-tools package, which should also be installed. The presence of pyrcc5 can be checked with which pyrcc5. Debian based systems need the extra package, and Arch does not. Scanning by filename or content with fuzzy matching to catch similar filenames.

    FDUPES

    FDUPES

    FDUPES is a program for identifying or deleting duplicate files

    FDUPES is a lightweight command-line utility that helps users find and optionally delete duplicate files within specified directories by comparing file contents, which can be extremely useful for cleaning up storage clutter or organizing large collections of files. It works by scanning directories and subdirectories, identifying sets of files with identical content through size and hash comparisons, and then listing them together so users can examine duplicates. Once duplicates are identified, the tool offers interactive deletion options where users can choose which copy to keep and which to remove, or apply flags to automate deletion while preserving a single instance. Because it operates directly on file content rather than just filenames, fdupes can accurately detect true copies and guide cleaning operations in data cleanup or migration tasks. It’s a simple, efficient, and widely used utility on Unix-like systems, appreciated by administrators, developers, and power users.

    qlsdup

    GUI based lightweight duplicate file finder / remover.

    Simple GUI based lightweight duplicate file finder and remover. Configurable file search and preview (via external tools) option for file data. No command-line interface available! This is basically a reimplementation of dupfinder as: it doesn't compile on my computer, the executable won't work either, the projects seems dead and I didn't wanna work through the original code. So Look'n'Feel should be somewhat the same, though some changes have been made. 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
