DriveDash indexes all your external hard drives, finds duplicate files across every one of them, and tells you exactly how to consolidate your storage — without moving a single file until you say so.
Plug in a drive. DriveDash reads its names, paths, sizes, and dates — nothing else. No file contents ever opened. No internet required.

DriveDash does not collect, transmit, or store any of your data. Everything stays on your computer. There is no account, no cloud sync, and no analytics.
When you scan a drive, DriveDash reads the following metadata from your file system:
DriveDash never reads file contents. No images are opened, no documents are read, no video files are accessed. Only the metadata listed above is used.
Nowhere. All scan data is held in memory for the duration of the app session. When you close DriveDash, the scan data is discarded. The only file written to disk is registry.json, which stores your drive labels and nicknames — nothing else.
DriveDash does not connect to the internet. It does not send analytics, crash reports, or usage data to any server.
When you use DriveDash to remove duplicate files, those files are sent to your operating system's Recycle Bin (Windows) or Trash (macOS). They are not permanently deleted. You can restore them at any time from your system trash.
DriveDash always shows a confirmation dialog listing the exact files before any removal action. Nothing is removed automatically.
DriveDash does not use any third-party services, SDKs, advertising networks, or analytics platforms.
DriveDash does not collect any personal information from anyone, including children.
