^^^^^^^^^^^^^
Just go to filemanagment on toolbar --> filemanager
Create a folder - then just select the files you want to move (multiple files keep ctrl pressed or ctrl+shift) important bit is move the mouse over (and click) the video option next to the name (the jpeg that indicates whether it is a video, text, rar etc) and move it to the image of the folder you want. Then it will deffo work
NB have to click on the jpeg and have to realease on the jpeg of the file you want - SILLY but IMPORTANT
