I have all my downloaded music in a file folder with different file folders within that for each album!!! Where do I put this folder so that itunes library recognizes it? All my songs used to be in my library but only 100 of 400 are now? thanks!
Check out the article to import the songs that are already on your computer. As long as you have the Keep iTunes Media Organized checked in iTunes preferences, then you should be good and then be able to delete the folder when the import is done.
