If you wish to extract files from multiple RAR archives at the same time you should have a look at Unrar Extract and Recover, as it also offers dedicated tools to deal with password protected archives.
Although you may find the interface a bit unprofessional, it does a great job helping the app complete the task of decompressing the user-defined archives. Truth is, a more user-friendly and modern approach is always welcomed, but it's still a good thing that everything's pretty straightforward.
You thus have to pick the input and the output directory and choose from the provided options which include remember input and output folders, delete the extracted RAR files, map directory to archive name, enable test mode or log password.
As you can see, Unrar Extract and Recover doesn't assault the user with too many configuration settings, so it takes just a minute before jumping into the main process of extracting files.
Besides the main window, Unrar Extract and Recover also shows a Command Prompt window that shows you a bunch of statistics, including the total number of processed files, successfully extracted, tested or failed.
In addition, Unrar Extract and Recover can very well be used as a password recovery tool if you provide a comprehensive dictionary file. The application can try each password for a user-defined list of archives, but this may take some time, just like it happens with a dedicated password recovery solution.
Unrar Extract and Recover works on all Windows versions and runs on low resources, but it may stress up the CPU and RAM a little bit when dealing with larger archives.
But overall, this is quite a handy tool if you deal with multiple archives at the same time on a regular basis and a simple visual facelift would turn it into a top product.
