Restoring multiple files from a backup

I backed up my computer preparing for a new one.  there are no backup "sets"...just documents, pictures, etc. mixed together as i just did a total backup of the selected files from my computer.  When i go to my backup all the files are listed but i do not see a way to select all or select multiple files...it looks like i have to do each one individually which would take forever (24gb).  is here a way to restore either the whole backup or select multiple files?
