Syncing duplicates tracks

[gkelson]

I've seen similar posts, but nothing that's answered my question.

Here's what happens:

1. I have the songs for Playlist A on both my android and my PC
2. I connect my android via Wi-Fi to Winamp
3. I set up Winamp to only sync Playlist A
4. I add one song to Playlist A on the PC side.
5. I sync my device.
6. Instead of copying only the new song, it copies ALL of the songs, so I have duplicates now on the device.

Other issue: let's say Playlist A is empty on my Android, but the track to be synced is on my Android, then when I sync I don't want Winamp to copy over the track. I only want it to add the track to the playlist so that my Android knows its on there.

Shouldn't sync only copy the actual files if they don't already exist on the Android device?

Thanks.
