I've installed UnRarX, now how do I extract files from the RAR Archive?
The easiest way to begin extracting your rar archive is to launch the UnRarX application and drag your rar archive into the main window.
Extraction fails with CRC Error
One or more of your rar archives may be damaged. If you have a par2 file that accompanies your rar files, simply drag your par2 file into the app window to begin the recovery process.
UnRarX can't extract rar archive or cannot write to File Directory?
In some cases, depending on the permission's settings on your computer Un RarX is unable to extract files from the rar archive. My advice in this situation is to try extracting the files to your 'Desktop' instead of the 'File Directory'.
