Can you include .3MF to the list of re-compressible formats? Its structure is similar to MS Office 2007 documents and Open Document Format. It is a ZIP Deflate archive with XML data and some JPG, and/or PNG pictures inside. Otherwise, if I try to compress .3MF it bearly makes it smaller unless I recompress .3MF to the Store setting then it makes it a lot smaller.
Wish they all would move to 7zip ZSTD in the first place so that the optimized file size with FileOptimizer would be 50% of the ZIP Deflate version. And there would be no extra compression needed :)
I noticed that the option to add the optimize archive function to the context menu is missing on Windows 10.
Opening each archive with the interface in order to click it becomes tedious with many files.
Same for others functions like Remove Archive Encryption
Support for RK and PAQ archives.

read this for paq
link for winrk archiver
archiver/compression test and comparisonsomeone recommended these formats for compression and from teh tests i can see why. i would find it very useful if PA could support them, sorry i dont have more info about the formats tho.

My thoughts:
Neither format is “free” for inclusion in other compression utilities. There is a license required for implementation (even though PAQ source is GPL).Note:
regarding WinRk - according to their forum, they do not even allow uncompressing by other utilities (never mind compressing)!regarding PAQ - so many variants (optimisations) which are incompatible, this is really a format just for experimentation.

A more accurate way of saying that is that we do not yet provide a way for others to implement RK archive support. :)
This may change in the future, however our main focus at present is on providing the best archiver we can. (As a hint, WinRK 3 should provide some interesting developments in this regard…)regarding PAQ - so many variants (optimisations) which are incompatible, this is really a format just for experimentation.
This is part of the reason we developed PWCM (and are currently developing the FPW family of codecs). The PAQ algorithms have great potential, but need more speed, format stability and usability.

I am not saying they are “bad” only that, as far as the original question is concerned (support within PowerArchiver) the answer is that neither is possible at present.

if we are on about formats how about par
and not forgetting uha which in tests is better than 7zip
