Dear PowerArchiver Users,

We are pleased to release the latest version of PowerArchiver 2019 – 19.00.32/33.


  • ZIP engine updates – Major updates to the ZIP engine. We have added several variations of both the encoder and decoder to speed up compression of files in fast and super fast levels, as well as optimized speed when 1 thread is used during encoding/decoding as well as a special decoder for highly compressed files. Added support for decoding files compressed with packmp3 in zipx. Overall a major update to the ZIP/ZIPX engine that will be explored in a separate article.
  • Removed ACE library – late last week vulnerability was discovered in old ACE library used in 32bit versions of PowerArchiver. Within 24 hours of report of the issue in another compression software, we have issued updates to all latest variations of PowerArchiver with removed library.
  • High dpi per monitor support – added support for configurations where user uses several monitors with different dpi settings.
  • Onedrive and other cloud engines updated – fixed access issue with Onedrive and updated engines for all clouds supported.
