For any type of data corruption in Windows 7 or Windows Vista, consider Kernel for Windows data recovery software. This process works for all zipped file types.
It doesn’t work under cygwin, windows opens up the zip file without asking for a password. Now that there is some functionality, it does not look for third party archive software and tries to do the operation itself, with confusing results. In the old days, Windows would always look for an installed program.
The recipient needs to install 7-Zip (or Winzip, or some other third party archive/encryption program), right-click on the file, and specify 7-Zip for the unzip operation. Windows recently built file encryption into the OS.
Microsoft doesn’t offer much help when it comes to providing information on how to password protect a file or folder. This “strong encryption” approach is much more secure than the original version, but it is less compatible because Windows and Mac cannot open them. More recently, the ZIP format was enhanced with the ability to create files with strong encryption, using AES. The ZIP file format provides support for basic password-protected ZIP files. Although ZIP files are by far the most common such compressed archive format, there are others, described below. The ZIP file format is notable for being both an archive file format as well as a compression file format. Update your operating system before running the command to install 7-zip file archiver.
These macOS-native apps are only capable of basic compression and extraction, and just for ZIP files. Unfortunately, that’s where Finder and the Archive Utility’s capabilities fall short. Some pro and power users might need to send an archive to a client or colleague in the recipient’s preferred format – or they might have a more complex compression task, like extracting multiple archived folders at once. war file? And what about other formats, like RAR, TBZ, TGZ, and 7z?
