I've been starting to use the 7zip-Zstandard version of 7zip.. With support for additional codecs that can be either faster and/or have a better compression ratio than lzma2 of the standard 7zip. (Site: https://github.com/mcmilk/7-Zip-Zstd )
Using the VFS Plugin, I am able to 'enter' into 7zip archives that use any of the new codecs. However when I try to, say, double-click on a .txt file for instance - I get an error stating: "An error occurred copying 'xx.txt' - the system cannot find the file specified. (2)".
I've tried playing with various combinations of replacing the 7z.dll and/or opus7zip.dll - as well as copying the codecs both into a "Codecs" directory, and also into the main "VFSPlugins" folder. But I still can't get it to open files contained within the archive. I have to extract it first in order to access the files.. Making it not-so-ideal.
I'm sincerely hoping that Dopus can support this, and yet have this plugin work in Dopus11. I'm disabled, in the middle of an 8-year disability case, and am now destitute with my sister helping for the bare essentials... So I absolutely can't afford to get Dopus12 at this time.
Some of these new codecs are used in large/major organizations, including Google and Facebook. So they're definitely mature and stable enough.
Please say that this is doable.. I'd really like to use these new codecs more often.
