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
PKZip compatible filename encryption
I understand that at least some versions of PkZip support AES encryption that includes encrypting the filename.
I currently use PAE encryption with PowerArchiver whan I want that type of encryption, but it would be nice to have the option of the PkZip compatible variant so that other programs that my correspondants might be using (PkZip and WinZip) can deal with such archives.
I also would like to see that feature.
