Is it possible to combine these accounts?

I've had the seemingly common issue with the last user and the 'other user' showing on the login screen, and once I finally dealt with it (well sort of, but that's another post for another time), I was back onto the standard user account I was missing, and was happy to be back with my old files. When I was dealing with that whole login issue I had been using a new account I set up that would work for the time being. Once I got this account back, I deleted that old account but chose "save files" (or some phrase along those lines) and assumed they'd be under the account 'Administrator'. But I looked on my files logged into Admin and in that folder, nothing is there.

So then, I typed in C:\Users\ in the start bar and found a list of ten or so accounts I managed to angrily make and use and not use in the last few months. All of them, one or two more than the others, have files I need. My question is this: Is there anyway to "combine" all the files from these accounts, since they seem to still exist although the accounts don't since I click on them from the list and up come the files, and have them on this account I'm logged into that I've gained back???

And I do not mean having the files "shared"....

Sorry for all the talking, it just seemed like on these forums as much info as possible is always good....
