A library to recursively compare files in two folders and return two lists of files: One with exclusive Files for the first folder one list with changed files between folders.

folder_compare also takes a list of Strings acting as exclude patterns using RegexSet.

Overall the functionality is comparable to a diff -rq folder1 folder2 -X excludepatterns.pat on unix like systems

For recognizing changed files, hashing with FxHasher is used.

Add folder_compare as a dependency to your project's Cargo.toml:

folder_compare = "0.3"


The following code recursively iterates over two directories and returns lists of changed and new files excluding those with ".doc" and ".txt" as part of the name/path.

use std::path::Path;
use folder_compare;

let excluded = vec![".doc".to_string(), ".txt".to_string()];
let result = FolderCompare::new(Path::new("/tmp/a"), Path::new("/tmp/b"), &excluded).unwrap();

let changed_files = result.changed_files;
let new_filed = result.new_files;
