Universal Extractor 2 (UniExtract2) 2.0 RC4 - October 2023 Update

Universal Extractor 2 is an unofficial updated and extended version of the original UniExtract by Jared Breland. It brings several hundred changes including community-wanted ones such as a batch mode, auto-updater and scan-only-functionality.

Unlike most archiving programs, UniExtract is not limited to standard archives such as .zip and .rar. It can also deal with application installers, disk images and even game archives and other multimedia files. An overview of supported file types can be found here.

Universal Extractor 2 is the most advanced unofficial modification around, aiming at the inclusion of many wanted features, improvement of current ones, ongoing support and a central open-source distribution. UniExtract 2 started as a simple modification disabling the always-on-top status box and ended with the addition of dozens of extractors to expand the range of supported file types. New – and unique amongst the available modifications – features like a scan-only mode to identify unknown file types using multiple scanning applications, the batch mode or the extraction of audio and video tracks from multimedia files make it stand out against these.

Virus warning?
Universal Extractor is completely free of malware. Certain antivirus programs may, at times, incorrectly flag files within the UniExtract program directory. Rest assured, this is a false positive—an erroneous detection. A more detailed explanation can be found here. If you encounter a false positive, please report it here.

As a short overview here is a list of the core improvements:

500+ new supported file types
Audio and video extraction for multimedia files
Cascading context menu

Support for some extractors not shipping with UniExtract as plugins
Resource usage/speed improvements, lots of fixes
First start assistant instead of installer
Full functionality available in no-install version
Auto-using 64 bit versions of extractors if supported by OS
