DatabaseThis saves the checksums created when using the search methods File content, Similar pictures and Similar audio files in a database. For further searches, the checksums are then determined from the database instead of recalculating them over and over again. This has the advantage that the time-consuming calculation of the checksums of files that have not been changed is no longer necessary and the search therefore takes considerably less time.
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.
- The database is not available on Windows XP.
- The database can only ever be used by one AllDup instance.
