Content-based duplicate detection for audio, video, and images. One fast scan across all your drives — then choose what to delete with complete confidence.
Every duplicate group is clearly presented. Preview files before deleting — nothing happens until you say so.
Finds true byte-for-byte duplicates regardless of filename, location, or tag metadata. Works across multiple drives in a single pass.
Intelligently selects which copy to keep per group — with full preview before anything is deleted. Clean thousands of dupes in one click.
Preview audio tracks, play video clips, and view images side-by-side before deleting. You always know exactly what's going.
Add as many folders as you need — external drives, USB drives, NAS volumes, multiple libraries. All scanned in parallel for speed.
Every deletion is logged with file paths, timestamps, and space freed. Export the log as CSV for full transparency on what was removed.
Find duplicate receipts, certificates, and scanned documents using OCR text matching — even when the images themselves differ.
Multi-threaded scanning engine processes large libraries without blocking the UI. A 500 GB scan typically completes in under 3 minutes.
Audio: MP3, FLAC, AAC, WAV, M4A, OGG. Video: MP4, MOV, MKV, AVI. Images: JPEG, PNG, HEIC, TIFF, RAW, BMP, GIF and more.
No cloud, no accounts, no telemetry. Your files never leave your machine. Works fully offline after the initial license activation.
"Scanned my entire 2 TB music collection in about 4 minutes and found 11 GB of duplicates I didn't know I had. The preview feature is what sold me — I could hear exactly which copy was higher quality before deleting."
"Finally a duplicate finder that actually works for video files. I had the same concert footage in 3 different folders and DupExplorer caught all of them. Freed up 47 GB from my video drive."
"I was skeptical about one-time pricing but this is the real deal. Six months in and it's still working perfectly, got a free update that added HEIC support. Exactly what software should be like."
