A two‑stage detection engine identifies duplicates with exceptional speed:

🧠 Smart Caching for Repeat Scans
Dedup remembers files and deep-analysis. If a file has not changed, there's no need to read it
again or analyze it again.
This makes repeat scans dramatically faster — perfect for Cloud storage, and external drives.

chunks. Put in as much time as you want and earn back free storage for every duplicate file you
delete.
