Feature: Added two new letters to details list attribute columns ("I" = "Not indexed" and "P" = "Sparse file").

Feature: When users elect to remove files during duplicate zipping, the actual file removal is now deferred until after the zip file is finalized / closed.
Feature: When Duplicate File Detective encounters a file system security identifier that is not mapped to an account name, it will now convert the SID to a string (e.g. it will present something like "S-1-5-21-9259032911-4949815421-2563717148-1001 " rather than displaying "unknown"). Note that "unknown" will still be presented if the security descriptor itself is inacessible.

v4.0 [Apr 20, 2011]
- provides deep support for duplicate songs (music files) through audio tag analysis. Supported audio file formats include MP3, Ogg Vorbis, FLAC, MPC, Speex, WavPack TrueAudio, WAV, AIFF, MP4 and ASF.
- provides a powerful system for comparing files through their hash values (e.g. checksums) - a process by which a file's contents are analyzed to produce a unique digital fingerprint. This duplicate file search technique is amazingly powerful and accurate, but can be time consuming.
- introduces an amazing new file hash caching facility that stores file hash values for later re-use. This feature can improve the performance of many duplicate search scenarios dramatically by eliminating the need to regenerate hash values for qualifying files.
- generates hash values for Zip files by expanding them dynamically and analyzing files they contain. This feature helps to ensure that zip files with identical contents are recognized as duplicates, despite any unique header values they may contain.

v2.2 [Apr 5, 2008]
Hash algorithm support makes the file comparison more flexible.
SmartMark duplicate marking system is improved for easy management.
The image preview is improved in this version.

v2.1 [Mar 6, 2008]
Integrated image preview, byte-for-byte comparisons, improved import and export features, and much more.
