There's a few things that are confusing me about what you wrote. Do you mean you are importing (you said you were exporting)?
What drive is the D: drive? Is it your 1TB external drive? Is it really a "backup" disk, meaning that the originals are somewhere else?
If my understanding is correct, and you are IMporting using Move, and these are backups that you are importing, then the solution is that you need to find the originals, which should be in the original folders. If these are not really backups, and you don't have actual backups somewhere else, then you are stuck with the new folder hierarchy, and no easy way to restore the photos to their original folders, other than by tedious manual effort.
Sorry if i didn't make it clear enough. I'll try better this time.
I'm not a native english speaker though, so that might also help to not being totally clear.
I'm transferring data from my external drive, the 1TB one, to one another one in my computer, the D:\ one.
Since i'm transferring from one drive to another using "move", i called it export. Wrong word?
About the originals, well, no, my backup is "the" backup.
Unfortunately, kind of expected that answer..
You can't move photos by exporting
You can move photos by importing IF they have never been imported into Lightroom previously. So ... are these photos you want to move previously imported into Lightroom, or not?
Nope. It was my first time using Lightroom.
My solution was to leave it be, because what i did was what i inteded to. (move all photos and videos to D:\)
The originals, well, since the "move" action in lightroom is nothing else but copy and delete the original, i had to recover what i wasn't suppose to mess around (my friends folder) by using Recuva..
So, i guess my problem (mess) is solved..
