Q: How do I open a ZIP or RAR file?

A: Opening a ZIP file is commonly called "unzipping." To Unzip a ZIP file:

  • Install 7zip
  • Now, right click with your mouse on the file you want to unzip
  • You can either click "Open" zipped file right now, or "Extract" the file to your computer
  • What's the difference between "Open" and "Extract?"
  • If you "Open" your file now, you can access it like a normal file. But when you close 7zip, the file will still be zipped-up and compressed.
  • If you "Extract" your file, it will become a normal saved file on your computer. Extracting is just like saving a full version to your computer! You can open your unzipped file at any time once you extract it.

Q: How do I UnRAR?

A:  UnRARing is just like unzipping. To UnRAR:

  • Install 7zip
  • Now right click on the file and choose "Open" or "Extract."
  • Exactly as outlined above, if you "Open" the file you can access it now, but if you "Extract" it the file will be saved to your computer and you can always access it later.

Q: How Do I Unarchive Other Files On My Computer?

A: Have other file types besides ZIP and RAR that you want to open on your computer? Simply use the same method to open:

  • Install 7zip
  • Right click on the file and select "Open" or "Extract"

Q: Why can't 7zip open some ZIP archives?

A: In 99% of these cases it means that the archive contains incorrect headers. Other ZIP programs can open some archives with incorrect headers, since these programs just ignore errors.
There are also some ZIP archives that were encoded with methods unsupported by 7zip, for example, WAVPack (WinZip).

Q: Why does drag-and-drop archive extraction from 7zip to Explorer use temp files?

A: 7zip doesn't know folder path of drop target. Only Windows Explorer knows exact drop target. And Windows Explorer needs files (drag source) as decompressed files on disk. So 7zip extracts files from archive to temp folder and then 7zip notifies Windows Explorer about paths of these temp files. Then Windows Explorer copies these files to drop target folder.
To avoid temp file usage, you can use Extract command of 7zip or drag-and-drop from 7zip to 7zip.

 Q: Why doesn't the command line version add files without extensions to an archive?

A: You're probably using a *.* wildcard. 7zip doesn't use the operating system's wildcard mask parser, and consequently treats *.* as any file that has an extension. To process all files you must use the * wildcard instead or omit the wildcard altogether.
