So apparently on a mac when you delete something from a USB stick it goes to a .Trash folder and even though it is deleted, it is still taking up room. I have my stick formatted to FAT32 for use between PC and mac. On a PC i see the .Trash folder and can delete thing permenantly, on my mac i cant, so have to formatt the USB pen every few days. This is becomong increasingly more frustraiting. Can anyone help?
