Convert RAR to AVI

It is unlikely that some way exists, which would allow users to convert RAR archives to AVI or some other video format. But pretty often you can find .avi files compressed inside a RAR archive, in which case you just need to decompress the content, no rar to avi conversion is required.

Simply put, it is impossible to convert RAR to AVI directly.
Thus, there is no so-called rar to avi converter or a free online .rar to .avi converter to be found.
