how do i delete music from my mp3 player from my pc music files

Step One
Connect the USB cable to your Sansa MP3 player, then hook the other end to a free USB port on your computer.

Step Two
Give the computer time to recognize the Sansa MP3 player. Once it has, double-click on the MP3 player’s icon to view the music files stored to memory.

Step Three
Scroll through the list of audio files until you find the ones that you wish to delete from the Sansa MP3 player.

Step Four
Click on single items or click and lasso multiple files.

Step Five
Right-click on the highlighted files to pull down an action list and from there select Delete. The computer will ask if you really want to throw the file away. Select OK.

Step Six
Exit from the window, then disconnect the USB cable from the Sansa MP3 player. The player will automatically turn off. The memory will update the first time you turn the player on after deleting songs.

I hope that helps!!

If you originally used rhapsody (or began in Rhapsody mode) , you have to use rhapsody to remove the songs. If that doesn't work, you can manually open the music folder by enabling "hidden folders" under "tools" -> "folder options..." -> click the "view" tab -> scroll and check "show hidden files and folders". Then go to My Computer -> Sansa e250 -> "system" -> "music" -> then delete the songs. I don't know the effects of using this method, so use it at your own risk.

Btw, Real Player should do fine as well.

you might want to try right clicking on your mp3 icon while in rhapsody and clicking format device...

If the 4gb micro SD is a high capacity SD (it will say micro SDHC on it) your player may not be able to read SDHC cards, my sansa can't because it's the 'older version' it will read 2gb and below micro SD cards though (it sucked when I found out because I had just bought a 6gb micro SDHC)

Have you tried re-formatting the device?  This will "wipe" memory, getting rid of corrupted files, etc. and should restore use.

go to www.download.com and search for a program called Unlocker 1.8.5 it's free... after installation, right click the file to unlock the file and it should be fixed to delete... I was on here cuase my unit froze...

Hi tater. Hmmm. The product category you selected is for a Standard E260. But if your player is an E250R (Rhapsody player), here's a set of procedures that might help you. Deleting songs from your E250R can be done in 2 ways: By using Windows Media Player 10 or 11, or by browsing the player through Windows Explorer. Before you delete files, though, it's important to know that your player comes in 2 modes: "Rhapsody" and "PlaysForSure". The reason why is that music files saved in one mode would not be seen in the other mode, and vice versa. Therefore, if you can't find the music files in your player, switch to the other mode. Here's how to do it: Use the "Menu" button to navigate the player as follows: Menu > Settings > Mode > This will give you the option of: "Rhapsody" and "PlaysForSure". Here's how to delete your songs: (1) By Using WIndows Media Player: > Plug your Sansa to your computer and open your Windows Media Player. > If your Windows Media Player is version 10, then click on the "Sync" tab and you should see your player ("E250R") on the right pane along with its folders, named "Data" and "Media" or "Music". Expand the "Media" folder and you'll see the "Music" folder containing your songs. Right-click on a song and select "Remove" to delete them. > If your Windows Media Player is version 11, then either click on the "Sync" or "Library" tab and you'll see your player listed on the left pane. The music files will be displayed on the center window. Right-click on a song and select "Delete" to delete the songs. (2) By browsing the player in Windows Explorer Note: the folders containing the music files on your player are "Hidden" and you would need to set your Windows Explorer to show "Hidden Files and Folders". Open your Explorer, select "Tools" on the top menu, select "Folder Options", select the "View" tab and enable the "Show Hidden Files and Folders" radio button. > Plug your Sansa to your computer and open your Windows Explorer > If your player is in "PlaysForSure" mode, then your player will be recognized as a "Portable Media Device". Double left-click on your Sansa E250R and you'll see 2 sub-folders named "Data" and "Media". Open the "Media" folder and you'll find sub-folders normally named after the Artist. Your songs are located on those Artist folders. Delete them by using the keyboard "Delete" key or right-click the file and select "Delete" > If your player is in "Rhapsody" mode, then your player will be recognized as a "Removable Drive" with a drive letter. Double left-click on your Sansa E250R and you'll see the following sub-folders: "Albums", "Music", "Photo", "Pictures", "Playlist", etc. Your songs can be found in the "Music" sub-folder. Delete them by using the keyboard "Delete" key or right-click the file and select "Delete" I hope this procedure helps. A bit lengthy but, hey, it worked for me (lol).

Use Windows Media Player
