Moving files (Documents) to folders in sharepoint 2010 is not a drag and drop thing. Actually it is a process. I still can’t figure out why it has to be so complicated for simple, not mentionning this stupid ribbon. How do you support such software? When things are all over the place.
Click on the library tab
Then click on open with explorer (good luck if you are using a MAC )
What i figured out after all is that if you use Sharepoint you are locked up to using only Microsoft technology. Editing a list requires Microsoft Excel to be installed. Moving Files to folders requires explorer and so forth. Google Docs kinda make sense.
