I have used the copy to and move to hack for years to right click on the menu to move and copy files. Never had any issues from XP thru 10. Now I have a weird one. When using external WD passport 3TB the last batch of files I copy show being moved (to a different folder on same drive), Next time I fire up computer same drive shows files never moved still in same folder. Cache issue? something else? thanks for any info....
