A simple Go tool to scan a directory for duplicate files (based on size and MD5 hash) and move them to a separate directory.

You can download the latest release from the Releases page.

Or install with Go:

go install github.com/arran4/move-dups-script/cmd/movedups@latest

movedups -src <source_directory> -dest <destination_directory>

• -src: Source directory to scan for duplicates. Defaults to . (current directory).
• -dest: Destination directory to move duplicates to. Defaults to dups.

Scan the current directory and move duplicates to dups:

movedups

Scan the photos directory and move duplicates to duplicates:

movedups -src ./photos -dest ./duplicates

1. Scans the source directory for files.
2. Calculates the MD5 hash of each file (including size in the hash key).
3. Keeps track of seen hashes.
4. If a file's hash has been seen before, it moves the file to the destination directory.
5. If the destination directory does not exist, it is created.
