Database

This feature enables you to store the calculated checksums during a scan for duplicate files into a database. That has the advantage that further file scans requires considerably less time because of the reuse of the stored checksums.

The storage of the checksums can be activated for the following search methods:

File content
A separate checksum is stored in the database for each comparison method. With 5 comparison methods, up to 5 different checksums can be stored in the database per file.
Similar pictures
A separate checksum is stored in the database for each comparison method and checked picture modification. With 9 comparison methods and 7 additional checks for possible picture modifications, up to 72 different checksums can be stored in the database for each picture.
Similar audio files
A separate checksum is stored in the database for each scan length and comparison method used.

Note: The database is not available on Windows XP.

Options

Recalculate checksum if the file size was changed

The checksum of a file will be recalculated if the current file size not match with the stored file size in the database.

Recalculate checksum if the file modified date was changed

The checksum of a file will be recalculated if the current modified date of the file not match with the stored modified date in the database.
