Backdown helps you safely and ergonomically remove duplicate files.

A Backdown session goes through the following phases:

1. Backdown analyzes the directory of your choice and find sets of duplicates (files whose content is exactly the same). Backdown ignores symlinks and files or directories whose name starts with a dot.
2. Backdown asks you a few question depending on the analysis. Nothing is removed at this point: you only stage files for removal. Backdown never lets you stage all items in a set of identical files
3. After having maybe looked at the list of staged files, you confirm the removals
4. Backdown does the removals on disk
