Right stuck again lol

Im on my new pc finall lol.

Ive got an external enclosure to put my other hd in and transfer files. Its all working fine untill i try to copy files over. I then get told i dont have permission to access. I go through all the crap to get access which works but then it asks for me to do the same for files in that folder too...theres hundreds of files so surely theres an easier way to do it than this? It will take 10 years if i have to go through the security thing for each file

Thanks in advance
