What's the use-case for WinRAR in 2023? I switched to 7zip over a ~decade ago and never looked back. Although I also have fond memories of using WinRAR as a kid and always felt thankful for the unlimited trial.
- better .tar.gz handling: Winrar treats it as one file, 7zip as a tar in a gz that have to be extracted separately
- recovery records to be able to recover from mild bit rot
- support for more NTFS attributes and features (saving alternate streams, security records, turning hard links into links, etc)
- can do useful things with the archive attribute of files if you so desire (archiving only files with the attribute set, clearing the attribute after, optionally deleting them)
- better GUI (7zip UI is an incomplete WinRAR clone)
- when selecting multiple archives, you can extract each to their own subfolder with a single command
Overall WinRAR is the much more solid archival tool. If all you need is something to decompress archives WinRAR isn't too different from 7zip, but has a slightly nicer UX.
This. 7zip it's amazing in its own right but some UX choices are weird like by default double clicking a rar file will not open 7zip (vs WinRAR that opens the preview what's files are inside, like any other program). Here you need to right click>7zip>Open in 7zip.
Not a huge issue, but I can see someone who installed 7zip, think didn't worked and then install WinRAR.
“Using Recovery Record slightly increases the size of your .rar files, but it helps to recover data should your file become corrupted by a virus, bad disc, etc. The larger recovery record allows you to restore a bigger damaged area, but increases the size of the archive and the process is slower."
I used this a lot in early 2000s when my only internet connection was at school or internet cafes, and the data transfer was via a bunch floppy disks I carried with me.
The floppies often had issues, so a single corrupted byte would normally corrupt the downloaded files (especially images and binaries) but with 10% or 20% of recovery data written in a non-damaged place, it could manage to un-rar.
If you're curious how this works: say you have some data like below:
You can calculate a sum of each row and each column, mod 2, and store it somewhere. When a single bit gets flipped, with the extra data (assuming the recovery data itself is not borked), you can calculate exactly which bit got flipped. (You can also calculate other kinds of extra data which can deal with more complex bit flips).
I seen this mentioned a few times in the thread. While true, there are other tools (with more control) for creating recovery data, notably, parchive[1].
Well first it was at a promotional price (~10€), for 24 hour, and was a dare with the 9gag community.
Also, from what I read in the comments and tweets, a lot of people who bought the licence did it more as a "thank you for all this year where we could use it for free"
And finally, as it was a promotion, the guy(s ?) at the end of the email adress had to make the links one by one and didn't had enough times to reply to all demands. If they'd planed it, with a dedicated page, I think the result could have been huge
That's a feature IMHO. Openness and interoperability is a bare minimum requirement for a general purpose archive format. RAR doesn't meet those requirements, so we'd benefit by having less people creating and distributing them.
