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
Version of compression format identification
I know this might not be possible at the moment but when you create say a rar or a zip file some encoding to the archive can inform you of the version of that compression format has been used.
For example you can tell if zip 2.0 has been used or if the 4gb zip has been used.
If the program can tell us which one it is for example it can help us find a program that can open it or get powerarchiver archiver to open it in future if it can not do so already.
This would need the help of all archive makers though it shouldn’t be too much trouble as it would eliminate the can’t open but your product sayes it can problem.
