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

I switch from IZArc to PowerArchiver because though IZArc supports making and decompressing almost all archive formats, its speed of making a ZIP archive or decompressing files inside an archive is too sluggish, and PowerArchiver is faster than WinZip, WinRAR and IZArc, also it has more funcitons. But later I found out that IZArc can not use thumbnail view insides an archive, like WinZip and ACDSee, XnView does.
Here are the evidences presented below:
Hope that PowerArchiver 2011 can solve this issue. :)

too late for PA2011, we do have nice preview though :-).
We could add this in one of the future updates, just keep reminding us!

(ie PA2011 is almost complete, we are solving last issues before public release candidate/beta)
