Description

Hi,

It would be create if ddup had a size limit filter?
For example --min-size=10G could have ddup run much faster by only looking at files of 10GB in size or larger.

A report with 1000s of small duplicate files isn't as useful to sort through.

Thank you!

Research direction

Start at ddup's command-line option handling and inspect how files are selected for duplicate analysis. Define the expected behavior for --min-size=10G, including size parsing and which files are skipped, then verify it with small and large files. The work is done when the filter speeds up ddup without changing results for files meeting the threshold.
