Good news for us WinRAR users, with the release of WinRAR 3.30 beta 1, QNX package file support is added. WinRAR now can open .qpr and .qpk files in one step, like it already does for .tar.gz archives.
WinRAR is a powerful archive manager for Microsoft Windows. It can backup your data and reduce size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format.
