GNKnow - File knowledge database for Windows

What is GNKnow? GNKnow is a file knowledge database. It remembers if a file is yet known. It checks for a folder with new files which files are already known by content and which are new. Even if the files are then archived on media or deleted, the database still knows which files were seen. The database stores only a fingerprint (about 100 bytes) per file to identify them later.
GNKnow finds identical files in two folder trees or duplicate files in one folder tree. Now with improved comparing speed. Resulting list of identical files can be exported as text document. Duplicate files might be deleted into file basket or experienced users might create own batch commands (.bat) that are called with every selected identical or known file.
Software Language GNKnow software is only available in English language.

Microsoft Database Jet Engine 3.5 must be installed if GNKnow tells that it is missing. It can be downloaded free.
Who should use GNKnow? GNKnow is used from hobby computer users collecting different kind of files (music, software, pictures...). Since many files are often distributed with different name again, GNKnow helps to remember which files were already seen. The known files can be deleted and the unknown files can be added to the knowledge database, then the known files are archived somewhere, the database from now on knows that they are seen.
