Fast data dupe finder
This is a small Rust command-line program to find duplicate files in a directory recursively. It uses a thread pool to calculate file hashes in parallel.
Duplicates are found by checking size, then (Blake3) hashes of parts of files of same size, then a byte-for-byte comparison.
Directly from crates.io with
cargo install fddf.
cargo build --release cargo run --release
Minimum supported Rust version is 1.39.0.
fddf [-s] [-t] [-S] [-m SIZE] [-M SIZE] [-v] <rootdir> -s: report dupe groups in a single line -t: produce a grand total -S: don't scan recursively for each directory given -f: check for files with given pattern only -F: check for files with given regular expression only -m: minimum size (default 1 byte) -M: maximum size (default unlimited) -v: verbose operation
By default, zero-length files are ignored, since there is no meaningful data to
be duplicated. Pass
-m 0 to include them.
