Can't delete duplicate tracks!

Try the following method to see what is on your Sansa e260

Hook up your mp3 player to your computer
Go to your desktop and double left click on "My Computer"
When it opens you will see listing that says "Devices with Removal Storage" your mp3 player should be listed there.
Right click on your mp3 player, and a window will open, right click on "Open" and now your files/songs should be visible.

If you want to delete some or all of the files do the following:
Hold the left click down and drag it across all the files/songs that you do not want this will highlight the files/songs you do not want, release, right click and then click on "Delete"
Now you mp3 player should be clear of the files/songs you do not want.
Good Luck,
I hope this helps

Use Windows Media Player 11 to delete those songs off of there - the Rhapsody downloads won't work after the 30-day trial has expired anyways:
To delete files from your mp3 player using Windows Media Player 10:

To delete files from your mp3 player using Windows Media Player 11:

My Directions:

1. Connect your mp3 player to the computer

2. Open Windows Media Player

3. Click on the icon of your Mp3 player on the left-hand side of the Library

4. Click on the Songs, Tracks, or other Music Folder

5. Find a song or songs that you want to delete

6. Left-click the song once to highlight it

7. Press the “Delete” button on your computer’s keyboard

Your DB might be corrupt. Folow the delete procedure one more time:
Delete Music Files
1) Connect your Sansa to the computer.
2) Select Open device to view files using Windows Explorer on initial
connection.
3) Select the place where you want to delete music files from
4) Highlight and delete the music file/s or folder from My Computer\Sansa
e200\...\MUSIC folder. (You can also select from a variety of music
software programs to transfer/synchronize your files).

If that fails, go ahead and update the firmware - it will delete everything, and allow you to start over from scratch among other things.

Uh, I had a similar problem which was extremely difficult to solve. What you want to do is reformat your entire MP3 player. YOU WILL LOSE ALL THE MUSIC ON YOUR SANSA. But you can simply resynch it.

Use Windows Media Player to delete those songs

Below are the instructions. I hope I've made them clear enough!
Make sure your device is under MSC instead of MTP...To do that go under Menu, settings and then usb mode...
--

Step 1
Open up Windows Explorer: Start > Programs > Accessories > Windows Explorer

Step 2
On the right of Windows Explorer, click on My Computer

Step 3
You should see two devices after your CDROM drive. One will be SANSA E260R and the other will be Sansa e200R Rhapsody. Chose the one on the top; the one that doesn't say Rhapsody. It may say E250R, E260R, E270R, or E280R depending on which model you have.

Step 4
Once you're viewing the device, you'll see the folders: PHOTO and VIDEO. These are the folders that contain your photos and videos. For videos, you can simply remove the video you want to delete - it will completely remove it.

I hope that helps

try and see if it is in MY COMPUTER if it is there download the newest firmware and update it if that doesn't work uninstall the mp3 player from your computer and then installit again.

i'm having a similar problem. every time i sync new music my computer tells me its on, but the tracks aren't on the player. it also refreshes every time i turn it on, which takes forever amd is getting really annoying. could this have something to do with my new microSD card?
