Good question. Here's why.
| Why not just... | What's hiding in your library? | CrateGuard |
|---|---|---|
| Finder / File Explorer | Matches filenames only. Misses everything saved under a different name. | CrateGuard hears the audio, regardless of filename. |
| Gemini · dupeGuru | Compares file hashes. Can't detect different rips of the same track. | Compares actual sound. Different rip, different bitrate - still caught. |
| Rekordbox / Traktor | No audio fingerprinting. No quality comparison. No health reports. | Quality scoring, health reports, and tells you which copy to keep. |
| Cloud-based tools | Requires uploading your library. Privacy risk. Subscriptions. | 100% offline. Your music never leaves your machine. One-time purchase. |

Questions & Answers
Does CrateGuard modify my Serato, Rekordbox, or Traktor data?
CrateGuard analyzes your library without modifying cue points, beat grids, hot cues, loops, playlists, or DJ metadata. Activated file moves can change paths used by DJ software, so review and back up before taking file actions.
How does CrateGuard detect duplicates?
It analyzes the audio rather than relying only on filenames or file hashes. This helps surface the same music when copies have different names, folders, tags, formats, or quality levels.
Will it delete files automatically?
No. CrateGuard groups potential duplicates for your review. Moving files or sending them to Trash requires activation and your explicit decision.
What does quality scoring mean?
Quality scoring compares available technical information such as format, bitrate, peak level, and file size. It provides context for your decision; it does not choose a file for you.
Does CrateGuard need internet access?
Scanning and analysis run locally and your library is not uploaded. License activation, periodic license verification, downloads, and software updates can require internet access.
Can I scan external drives or NAS locations?
CrateGuard can scan accessible folders on external drives, USB devices, SD cards, and mounted network locations, subject to operating-system permissions and the connection remaining available.
