A common problem is that you need to open a file, but you don’t know how. If you’re on a Windows PC or an Apple Mac, this app is your solution. It can open almost any file and will let you view the contents.

With this app, you can also extract a RAR or ZIP file. It’s very easy to use, and you don’t need to know anything about the file format.

The main thing is that it’s free, so there’s no need to worry about any kind of payment.
