You need to get a RAR file converter. For Windows, you can get a 40 day free trial from RAR Labs - See the Related Link below. You may also need a password - that would have to come from the person that supplied the original RAR file.
The person who sent it to you or uploaded it needs to tell you it. Otherwise, it is virtually impossible to open it.

You cannot open the file unless you have been supplied with the correct password.
Use a program that can extract .rar files such as WinRAR or 7zip.
You can use WinZip or WinRAR to extract the files. Files with the asterisk also require a password.

That's not possible, because the password is used to encrypt the data inside the WinRAR archive. The only way to change the password, is to extract the data from the current WinRAR archive and then to create a new WinRar archive with the new password.

Winrar
A WinRar for Mac is a type of program that backs up your files on your mac and it can also decompress ZIP, RAR, and other files. It's an archive manager.
You must first compress your files by zipping them or by using a program such as WinRAR to put a password on them. To Zip them, right click on the files you choose and click Send to, Compressed file. Under the Security tab, create the password you choose. As it compresses, it adds the password on it.
WinRAR can read and extract files from program installers (ie. Setup.exe). It cannot open just any .exe file in general, though.
You can make an archive using winrar or other program. When you install winrar, you mark the files--> right butoon--> add to archive,and they`ll be ready :)
