Easier way to extract several parts of movie?



i have a backup of a disc and there are 40+ parts to each disc (2 disc) this is taking me forever doing it one by one. is there a way to extract all the rar files at once?
they are filename.part01, filename.part02
when i extract one by one i click yes to replace all and this will work as i have done it before but i would really like to find an easier way to do this. i am new here as i am sure you can tell and i dont know how detailed you need me to be. hopefully you understand my question. if not i will provide additional details. thank you all


nm. i found it on google. apparently i was told the wrong thing to begin with. i have been trying to extract each file one by one and i only have to do the first one. …Geesh!
