Paq9a archive support

Help & Support

I found some paq9a archives on the web and after doing some investigating it seems there is no GUI support for these as yet.

Any chance it could be added to Dopus' archive support?

Where is this format used, and why? I’ve never heard of it before, and the GitHub page says it’s “experimental” which makes me wonder if it’s intended for general use.

Hi Leo,

I've only seen it used on some old ISO rom files.
490MB compressed to 9MB for example.
After having seen that, I would like to try it out further.

Try recompressing them with 7z. I bet the size is similar. The files are probably mostly empty to compress that much with any algorithm.
