Unlock fast and easy

Hey
I just bought a new WD passport external harddrive for my macbook pro and formatted it to FAT32 so i could transfer my files between my windows computer and this computer. Anyway, the problem im coming across is when I upload the info (mostly pictures) to my mac it locks all the files and i must unlock them all... most of them are in folders which makes it more difficult because i cant just select the "get info" for the whole folder to disable the lock. My question is.... Is there a way to unlock files in whole folders or some sort of hotkey that makes unlocking files fast and easy??????

Thx, BlizZ
