For the example I use my music video collection directory.
For next actions look at the screenshot:
After this actions ParNRar will check and unrar files.
!!!Every directory must contain .svf file for checking and unraring files!!!
All unrared files will be in default directory! ParNRan doesn`t move unrared files.
When job is done you can find your .rar files inside Recycle Bin (clean up it) .
