Sorry if this has been posted before, I looked in the forums but couldn't find a solution to my problem.
I'm trying to move files onto a USB but it starts copying the file then the green bar just stops and won't go any further and I eventually have to CTRL ALT DELETE - task manager - end program, to get rid of the window. I tried it again with my external hard drive to the same result. I can copy and paste files on my computer though without any issue.
The weird thing is it has been doing this on and off for a month, with some days it works fine and some days it chooses to be difficult.
