From windows I've copied a number of files. They are of .tga and .psd files, but when I transfer those file in my thumbdrive over to mac pc.. I found a difference in total filesize. Strangely, the file size become smaller when i copy from Mac to PC. And when its from PC to Mac, the file size remain the same... But then when .mov files are transfer over instead the size remain the same for both mac to pc and pc to mac.. What are the possible cause of this event??
