I have a rar file with password protection. I forgot the password. Is there any way to find or remove rar file password without brute force or dictionary attack ?

No. Otherwise the presence of the password wouldn't matter at all.
Update: "WinRAR offers you the benefit of industry strength archive encryption using AES (Advanced Encryption Standard) with a key of 256 bits." And, according to some calculations, using a considerably impossible amount of modern GPUs (one billion), "it would take ~6.7e40 times longer than the age of the universe to exhaust half of the keyspace of a AES-256 key."

Wasn't the answer telling clearly enough that it is not possible? – Tero Kilkanen Oct 29 '16 at 10:03
