One of the four basic Libraries is Music. I found thousands (yes!) files in that Library, most of them I have no idea about and have absolutely nothing to do with music. Windows said they are references and deleting them will not remove the actual file from the PC. I found that incorrect, I deleted a .jpg file (Picture) from there and it is also gone from the C:\users\myname\pictures\actual picture folder. I had to reclaim it from the Recycle bin. Why are all those "references" there? Windows Explorer is just one needs. Do they load up the memory and just make things even more confusing? How can I get rid of them and not jeopardize the actual files in the C:\users|....? And why they show up in the Music Library when they are nothing to do with music? Windows 7 Pro or not Pro has a lot confusing items. Are they there just to promote a "new" version to be purchased? (Beware of Windows 8) Sometimes I long for the good old XP.
