Yes that's what I'm using right now, you should load the software that came with the player if you have and simply use Windows Media Player to create a library of songs from which to choose, when your ready connect your device and clisk on the SYNC tab then this will allow you to pick songs or whole albums to the right sync column, when this has everything you want click the START SYNC tab and it all will load into your player.

There are two sets of solutions that you may need to apply.
1) Disable Auto-Sync in Windows Media Player. This is how the songs may have been loaded in the first place. Connect your mp3 player to the computer and open Windows Media Player. Run the mouse over the "Sync" tab - a black arrow should appear - click on the arrow. Click the option that says "Set Up Sync" and uncheck the box that says "Sync Devices Automatically".
2) Delete songs using Windows Media Player. Click on the Sync tab. Find the songs that are loaded onto your mp3 player by clicking the icon that represents your mp3 player. Highlight the songs by left-clicking a song once, and press "Delete" on your computer's keyboard.

Good luck!

I do mine through Windows Media Player
1)Plug in Sansa
2)Open up Windows Media Player and wait for the Sansa e250 icon to show up under the library. First time, might say 'What device is this' or 'Autoplay'-for autoplay,you click 'sync media files to Sansa e250 using WIndows Media Player'
3)When library shows, click 'Sync' if it is not already there.
4)Just simply click and drag the songs you want from the computer library to the list pane on the side.
5)Once your done, click 'Sart sync'

TO DELETE
1)Plug in
2)Wait for the icon under Library in WIndows Media Player
3)Go to Songs under Sansa e250
4)Right click desired songs and choose Delete. You only want to delete from Sansa e250-nothing else

okay, first thing you have to do is make sure you have songs in windows media player.  if you do not,  you will have to insert audio cd's into the computer and rip them from the cd's onto the computer.  to do that you must put the cd into the computer, and when windows media player comes up go to the rip tab and fin the button that says start rip or copy.


once you have the songs in the computer, you will have to plug your player into the computer.  windows media player will find it and take you to your library. if you are using windows media player 10 or lower, you will have to select your songs by holding down control and clicking on the songs you want to sync.  once you do that you must right click on one of the while still holding down control button on the keybord.  the click on add to sync list.


if you are using windows media player 11 or higher, you must click on the sync tab at the top of the screen and look to the left.  there will be a list, and in the list it will say library.  in the library list it will say songs, clikc on that.  follow the steps above for selecting songs. once you have the songs selected you must drag them over to the list to where it says SANSa e260 or whatever you device is called. once you have all the songs dragged over, you must click sync to player from the window on the right of the screen.  after it is done the songs will be on the player.

if something is not clear leave a comment on your page and i will explain it for you
