duplication between shared folder and itunes

[sdmorgan]

I'm running Limewire on an eMac, OSX. I transfer all of my downloads from my shared Limewire folder to iTunes. I also have my iTunes library in my shared folder so I can share my CD collection. My question is: am I duplicating alot of MP3 files. Can I delete the downloaded ones in my shared folder after I transfer them to iTunes. Once I transfer them to iTunes are the files "there" without them being in the original shared folder? It seems that I'm taking up alot of space by having the same stuff in both places. I don't understand computers enough to know for certain. I figure if I transfer things to iTunes than I can delete individual files from my shared folder and still share everything since my iTunes library (where the files have been transfered) is also in the shared folder. I'm confused. And probably confusing. Thanks for any help.
