fclones-gui – interactive duplicate file finder and remover

Last Updated on March 8, 2026

fclones-gui is a graphical user interface for fclones, a command line utility that identifies groups of identical files and gets rid of the file copies you no longer need.

The front-end is in an early stage of development.

This is free and open source software.

Key Features

  • Identifying groups of identical files:
    • Finding duplicate files.
    • Finding files with more than N replicas.
    • Scanning multiple directory roots.
    • Filtering names and paths by extended UNIX globs.
    • Filtering by min/max file size.
    • Proper handling of symlinks and hard links.
    • Optional ignoring of files specified in .gitignore.
  • Removing redundant data:
    • Removing, moving or replacing selected files with soft or hard links.
    • Removing redundant file data using native copy-on-write (reflink) support on some file systems.
    • Bulk selection of files to remove.
    • Prioritizing files to remove by creation, modification, last access time or nesting level.
  • High performance:
    • Parallel processing capability in all I/O and CPU heavy stages.
    • Automatic tuning of parallelism and access strategy based on device type (SSD vs HDD).
    • Low memory footprint thanks to heavily optimized path representation.
    • Accurate progress reporting.
    • Uses modern GTK4 list controls that can display hundreds thousands items.
