how do i save or put my downloads in the save folder of the library???

i thought if i emptied the shared file it would move them to the saved file.

this did not work. instead i lost half of my downloads.
this happend last night. the next day i moved some files into the play list, and about an hour later some of the files i thought i lost last night reappered in my saved file.

this is confussing to me probably as much as it is to you.
But if anyone has an idea of what is going on help is greatly needed
