IObit Undelete

IObit Undelete is a lightweight file-recovery utility for Windows that looks for files removed from a drive, whether through accidental deletion, formatting, or loss caused by malware. It works without requiring the user to have set up a backup beforehand, scanning the target location or device directly for recoverable data.

The tool offers a targeted scan for quickly checking a specific folder or drive, and a deeper scan mode intended for files that have been missing for longer periods, where recovery odds are lower. Before restoring anything, it rates each recoverable file's condition (excellent, good, or poor) so the user can judge how likely a full, uncorrupted recovery is. Results can be filtered by filename, file size, and extension to make it easier to locate a specific item among scan results.

A portable build is available that runs directly without installation, which is useful when recovering files on a system where installing new software risks overwriting the very data being recovered.

This is a narrowly scoped recovery tool rather than a backup solution: it does not create or manage backups, it only attempts to retrieve files that are already gone. It suits users dealing with a one-off accidental deletion or a formatted drive, not people looking for ongoing data-protection software.
