Do you want to unzip or uncompressed files with a file that has a .rar extension and you have a windows computer? But you want to do it for free without having to pay any money for expensive software? If so, read on. This is how I did it, there may be other ways, but this is the free way, not necessarily the easy way but it works.

This is what you will need:

1. A PC with windows (I am using windows 10)

2. Virtual Box installed

3. Ubuntu Linux

4. A .rar file

Ok, now that you have all these requirements, this is how you uncompressed the files.

1. Make sure to enable Share Folders in your Virtual Box with your computer

2. Run the Linux virtual machine

3. Open the command line

4. Install unrar with the following command:
$ sudo apt install unrar
> Provide Password

5. After the installation has been completed. cd into the share folders in the linux virtual machine. For example, I sent this command in my machine:
$ cd /media/sf_HTDOCS-udacity/UNZIP

6. In the windows PC (Host) place the .rar file in the shared folder. For example: F:\apachefriends\xampp\htdocs\udacity\UNZIP

7. Now comes the BIG part, uncompressed the file with this command:
$ unrar x fcade_sf2cet_2.rar

8. You will get a message that looks like this:

react@react-VirtualBox:/media/sf_HTDOCS-udacity/UNZIP$ unrar x fcade_sf2cet_2.rar

Extracting  fcade_sf2cet_2.lua                                        OK
Extracting  fcade_sf2cet_2.bat                                        OK

Thats it, now the files will be available in your windows file explorer!
