My kingston 4g usb data traveller drive could not copy correctly

if you copy one folder should be the same,anyway the .pls is for playlist for winamp  so you need to check if you maid some settings regarding some association ,try to copy first with folder to folder but not in the total commander but in my computer this shold resolve your problem ,and i advice you to reinstal total comander with defalt setting if you tried with that.
