I am trying to convert all the WMA files on my computer to Mp3 so that I can share them with both itunes and zune. Any tips for keepign things cleaned up and not having duplicate files everywhere?

Is there a way to have itunes delete the WMA file after creating mp3 copy?

No. But after the MP3s are created and you are satisfied that things went OK, just delete the WMAs manually and say "Good Riddance."

You can use an MP3 in multiple players, but you need to turn off any features that automatically change or move files, since one player will change something that messes up the other:

• In iTunes, that means go to Edit > Preferences > Advanced and uncheck "Keep..." and "Copy..."
• In Windows Media Player, that means go to Tools > Options > Library, and uncheck everything that starts with a verb such as "Rename...," "Rearrange...," etc.

Are any of them "Protected WMA" rather than normal WMA?

In Windows, Set the "View" to "Details," and look at the Type.

M King,

When you let iTunes do the conversion, it puts the files in folders according to its own rules.

One way to avoid that is to do the conversions with a 3rd party program (such as Switch), put the new MP3 files in folders the way you want them, and then add to iTunes. (This approach requires "Keep..." and "Copy..." to be turned off, as previously mentioned.)
