7zip is free winrar

You likely want the first one in the third category (7-Zip 23.01 (2023-06-20) for 64-bit windows x64)
It's by far the most common archiving software gamers use besides winrar because it does the same thing and handles the exact same formats but it's free.
Viewing post in how tf do you think i can open this shit?
Since it also sounds like you might not know how to use archiving software, after installing it simply adds a 7zip context option to the right click menu. Right click the zipped folder, go to 7zip's options, and "extract to (folder name)"
Do not use extract here unless you want the files dumped where the folder is, instead of in a new folder.
