File dedupe and unify toolkit, shown as " " in the DSH sidebar: exact matches by head/middle/tail sampling or full byte compare; near-duplicate MP4s found by a prefix frame-level multi-candidate matcher (only the first N seconds, default 40, max 60; a frame-level index plus multiple candidate tracks handle shifted intros and repeated segments), with a SQLite fingerprint cache keyed by absolute path and size so rescans skip ffmpeg; batch rename or move by extension, UUID, file size or video length; empty-folder cleanup; MOV/AVI/WMV detected by header and transcoded to MP4 keeping resolution, frame rate and audio. Requires ffmpeg and ffprobe. Scans run in a sidecar worker with live progress, A-B single-direction dedupe and asynchronous fingerprint writes; one task at a time; local-only API. Every task that moves files has one-click restore: per-group/target _dupfc_restore.json records, deleted files skipped and counted, files outside the record renamed to UUID and moved into resetFail.
