You can use the online service to recover the password first and then unrar the file manually. One good example of such an online tool is Password Online Recovery.

Step 3: The recovery process will be initiated as soon as you activate it.

Step 4: Once the recovery process is completed, you will be prompted to fill in your payment details for the payment (service charge is 10 Euros) in the "Payment and Confirmation" section.

Step 5: Once payment has been successfully confirmed, you'll be taken to the "Get results" page where you can download the password to unrar the password protected file.

Although this is a handy tool available online, there are certain downsides of this online approach:

  • You need to upload your file which means there is a chance of data privacy leakage.

Approach 3. Unrar Password Protected File with CMD Prompt

This is a totally free-of-charge method of recovering the password of a RAR file. However, this approach is relatively complex, especially for regular users since you need to enter a few lines of command.

Below is a step-wise procedure to unlock the RAR file using the CMD Prompt:
