Windows had native ZIP files in Windows Me, actually. http://www.windowsnetworking.com/j_helmig/winmezip.htm It was called "Compressed Folders" and it was an optional component. Back then, Microsoft was a little less pushy and unlike the garbage that they were using to destroy companies with like Internet Explorer, some things didn't actually have to be installed. (IE/Trident could be removed too, just not officially.) Microsoft gotta Microsoft, so of course it had a horrendous and completely stupid security vulnerability. It saved your encrypted ZIP passwords in a plaintext log file on the hard drive every time you made a password protected ZIP file. https://download.cnet.com/Windows-Me-Exposed-Passwords-in-Compressed-Files-Vulnerability-Patch/3000-2092_4-10058010.html Daemonfc (talk) 00:19, 22 July 2020 (UTC)
