PAQ 6

PAQ 6 is one of the lossless data compression archiver that belongs to the PAQ series. This utility can run on various operating systems like Windows, Linux, and UNIX and it has earned the reputation as one of the top data compression archivers when it comes to memory and speed. This sixth version of PAQ is mainly aimed for fostering the development of algorithms and data models that are expected to be better. PAQ 6 has the ability to assume that if the archive already exists, users would want to extract them but it can also perform comparison and reporting to determine whether the files are similar especially if the files to be extracted also exist along with the files to be compressed. This PAQ version also features conversion versus memory and speed trade off and this also comes with upgraded versions such as PAQ6V2 which has added ability especially when it comes to correctly decompressing files that the PAQ6 compressed.
