Why won't iTunes sync to my iPhone? - 1

I copied my whole itunes folder to an external drive as id run out of space on my PC. I then changed the location of the folder on iTunes through preferrances, but it gave me a warning which i just pressed no/cancel to without reading it, but i didn't realise that then it had not saved the new folder location. When i deleted the original folder, everything dissappeared from itunes meaning i had to reload everything from the new, moved, itunes folder. This wasn't a problem, except it had lost all memory of playlists and play counts etc. But now, when i try and sync my phone, it tells me there's not enough space on the phone as it must be trying to add all of the music from itunes to the phone as well as what is already on the phone.

Is there a way to upload everything from the phone to itunes, including play counts and playlists?

if not…

How do i just sync my phone to itunes without having to reset the phone and losing photographs, and without itunes trying to add everything twice?

Last question, why do Apple want to make this so difficult for me? What is wrong with plane old 'click and drag'?

I'll try and help as best as i can. Your answer about itunes already adding stuff that's on your phone, i know in itunes you can check or uncheck automatically sync songs/music to your iphone, if you uncheck this then music will not be transferred to your iphone unless you do it manually. Try un synching your phone from itunes by clicking on the button you click to disconnect or right click on that button and left click eject, after that unplug the usb cable from your pc/laptop and plug it in again see what happens from there. Sorry i can't be much more help. Forget the part where i said about un synching as you could not sync with itunes in the first place but try the other things i mentioned.
