 - Renames video files to match, and organizes TV episodes into `S01`, `S02`, etc. season folders
 - Detects loose movie or TV episode files sitting directly in the share root (no folder of their own) and organizes them into a proper movie or show folder
 - Detects a duplicate show folder for a show you already have (e.g. a separately-downloaded "Show S02" folder) and merges its episodes into the existing show folder instead of creating a second one
+- Detects a duplicate movie folder (a re-download that resolves to a movie you already have) and moves it into a `DUPLICATES` folder at the top of the share, rather than overwriting or leaving it loose. Cleanup (`-c`) picks up `DUPLICATES` and moves it to trash the same as anything else
 - Checks your organized TV shows against TMDb's episode list and reports any already-aired episodes you're missing (`-e`), without changing anything
 - Understands anime-style absolute episode numbering (episodes numbered 1, 2, 3... straight through instead of per-season) when TMDb has that show's episode order data, converting them to the correct season/episode automatically
 - Finds subtitle files, figures out which one matches your primary language (by filename, and by reading the file's content/metadata if the filename doesn't say), and renames it to match the video. Defaults to English, but follows whatever language you've set for TMDb results (see [Non-English users](#non-english-users)).

 - **Nothing is renamed without asking first**, unless you pass `-y`.
 - **Every rename is logged** to a `logs/` folder created next to the script.
 - **Cleanup never permanently deletes anything.** Matched files/folders are moved to a local `.trash/` folder, not deleted, and you're prompted per item unless `-y` is used.
+- **Rename never deletes anything either.** A duplicate movie folder is moved into a `DUPLICATES` folder on the share, not removed. It only leaves the share once cleanup (`-c`) moves it to trash, same as everything else.
 - **Undo anytime** with `-u` (most recent run) or `--restore <logfile>` (any past run).
 - **Your TMDb API key is never uploaded anywhere.** It's stored locally in a `.env` file, which is excluded from Git via `.gitignore`.
