Library & external drive problems

Hi. Looked through support & tutorials & can't seem to find an answer. Hope you don't mind me asking here. In XP I could monitor my Windows Media Player music files/folders to my external storage drive.That's where it would look & update them from the locations I specified. In Windows 7 no matter what I've tried to do so far it also creates these files/folders in my music library folder. If I delete them from there it also deletes them from the external drive. We're talking about approximately 4,000 mp3 files. This causes unnecessary wasted space on my hard drive. Is this a library problem & is there a workaround for it? I can't monitor my file locations through options in Windows Media Player anymore. I have to do it through the library folder. Can the default library folder be deleted? I think that's where the problem is but I'm guessing at this point.
Windows Media center creates another problem in that it will let me specify what locations to monitor; music, photos, etc. but when Wmc & Wmp are both enabled in Windows features I get an error saying "an error has occurred.
Not all of the features were successfully changed." Anyway that's what I'm trying to resolve. Thanks for listening & I appreciate in advance any help or advice you might have.

Thanks WHS. I already tried that. Changed my default music location in the music library folder to my F:\ drive which is my Seagate Free Agent storage drive. All my music still replicates itself in the music folder. And worse yet, when I delete the files from the music library folder on my hard drive it also removes them from Windows Media Player! Very strange. And the music library folder is then empty & asks for a default music location. I'm not sure but I seem to recall when I used WMC to set up my file locations that were in the external drive they didn't duplicate themselves to the hard drive. Can't be sure though because of the error problem when enabling both WMP & WMC. Seems I can't have them both enabled. Thought of going back to WMP 10 or 11 where folder monitoring is done in the player's options but with the way Windows 7 behaves I will need to back up my Seagate drive to dvd's first. I still don't understand the reason for having a library at all. Can it not be deleted. Any thoughts? Thanks

Sorry if I wasn't clear on this. OK, my default location for all music mp3 files & folders are located on my external Seagate drive. How do I specify that my default folder location is located on drive F:\ through Windows Media Player when that option to monitor folders is no longer available in WMP. Now, when I remove the default music folder from the library all music in WMP is then rem oved & I'm asked to Click organize & then manage libraries to include folders in WMP & the only options are the default libraries located on the hard drive. After I do that WMP then becomes re-populated but also adds all the files/folders to the default music library folder. I know it's confusing WHS. I believe in keeping it simple myself. I just need to be able to have WMP point to the external drive without having to go through the hard drive in order to populate the music into WMP. As stated earlier, this can no longer be done through the monitor folders option in WMP. I hope this provides a better understanding of what is happening. I really am thankful for your patience. It just seems that what once was simple is no longer simple.

Followed the screenshot & that didn't work either. Music files are still being replicated. But I do thank you for all the help. Every other tutorial & customization on the site has worked out great. This is an invaluable site & I thank you again WHS for all your help in trying to resolve this problem.
