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
Add Microsoft SZDD CAB support

Hi, today I was modifying some nVidia driver files, but they seem to have SZDD compression. PowerArchiver is not able to open this files or even extract them.
I have no further information about this compression mechanism, however I do know I can extract those archives using Microsofts Expand tool.I would like support for this compressiontype. Also other driver packages have sometimes SZDD compression.
Here some History
CAB History
In 1977, Abraham Lempel and Jacob Ziv devised and published a paper on their new compression method, LZ77. In 1982, James Storer and Thomas Szymarski released their LZSS variant. In the early 1980s, Microsoft required some form of data compression for their installation media to cut down on the number of disks needed to install MS-DOS and Microsoft Windows, so they took Haruhiko Okumura’s implementation of LZSS. Their compressed files had a SZDD signature.Also a link with lots of information: http://www.kyz.uklinux.net/cabextract.php
