How it works

  1. Select local files in File Explorer.
  2. Press Alt + Space and type “Create Checksum File”.
  3. Choose the checksum algorithm. A checksum detects changes but does not prove who created a file.
  4. Start the action and check the result.

A practical example

Record checksums before transferring files, then verify them afterwards.
