ashampoo-undelete-recovery preview

Ashampoo Undeleter: Windows file recovery and drive scanning security tool

  • Sector-Level Disk Scanning: Ashampoo Undeleter reads raw sectors of the target volume to locate file records that remain after deletion, rather than relying solely on the file system index.
  • Recovery Quality Ratings: Every detected file is classified from Good to Lost based on the integrity of its remaining data, so recovery priority is set by evidence rather than guesswork.
