"Today I downloaded a cabinet file whose format is RAR
from the web. Just as I was trying to extract the RAR file, it asked
for password. I looked for the extracting password from the website
where I downloaded the RAR file, but didn’t find it. Now who can tell
me one way to unlock encrypted RAR file without password? Any RAR file password cracking software or tool is OK. But make sure it has no virus. Thanks in advance."
