If it's anything like their zip functionality then it won't support encrypted versions of those formats. I'll be keeping WinRAR in any case.
Old, and i do mean OLD Winzip and up-to-date 7-Zip working just fine here. No need for natively now when they could have done that ages ago.
I assume they are doing it now to expand the Linux subsystem support. Particularly the .tar and .gz part.
People have to install 7-Zip to get added file format functionality the Windows 11 native zip utility doesn't currently support.
winzip got bloated about 20 years ago. even it “sophisticated” features never wont make me buy a license. 7zip is nice, but rar (paid) has a some more features i like and use (command line). at least winrar dominates my packaging beheavior.
I've used 7-Zip for years (decades, I hesitate to say), and will likely continue to do so. Microsoft missed the bus on that one years ago.
I'm using Total Commander as my file manager and haven't used windows built-in zip functionality (or 3rd party software) for ages. It will probably be OK for those that don't need advanced features and have data in 7z files.
Defender can scan a lot of archive file types, so why not offering same for explorer? maybe with a small fee!? "natively" means extracting and packaging with no options as mighty winrar or 7zip offers. thats similar to zip.
Latest bit of reading on the rar native support update in Win 11 and how it compares on extraction to other softwares. https://www.neowin.net/news/windows...-is-how-it-compares-to-winrar-and-other-apps/ (If you have a few minutes to spare read the comments under the article... gets a bit.... heated )
decompression is futile, someone need to create rar archives and winrar is the best choice for it. 7-zip cant, so i assume that nanazip cant do too.
Not a lot of info on the samples they used. On all of these the extract modules should be open source. The encryption modules not so much which is why it doesn't support passworded files. Files from the internet with the "Mark of the Web" can be a point of inefficiency with some of these. If you extract an archive with this mark most of the software today will add that to all of the individual files in the archive upon extraction. If you have not optimized this process it will slow things down. Possibly a lot. If you trust the archive you should "unblock" it first. It will save some time when there are a lot of files in the archive.
at least 7z and rar have similar packaging rates, but as i wrote in may rar has a lot more switches. major switch when backing up is the date switch which is not available in 7zip. on the other hand rar cannot archive as 7z (and vice versa) and 7-zip has some advantage with the filemanager to open any file if possible. so i use both.
