Putting Music on Player

I’ve had my mp3 player for about a month and its the first one I have ever had. I was just wondering if there is a way to keep the music on the player when I connect it to my pc. Everytime I do it deletes all the songs on my player. Someone told me I need to keep a backup file of all the songs I download, but my storage space on my pc is small and I delete the songs after uploading. If anyone could please help that would be great.

You’ve probably got Windows Media Player set to Auto-Sync. Change it to Manual in the settings.

Or switch to MSC & take WMP out of the equation altogether.
