Does anyone have that? Is it free? I need it to open my game but
dunno should get or not.
1. It's pretty common nowadays.
2. It's not free. But you can either stay with its trial version
after the first 30 days and bear with a nag message every time you
use it, or find a pirated copy.
3. As FI has said, you can use 7-Zip to open RAR files, and it's
free. But 7-Zip seems to be taking up a lot of resources when
compressing and decompressing archive files as compared to
WinRAR.
