What music file?

are you able to see all your music files in your sansa player? if yes, try to play those songs from your mp3 player. then you can format your mp3 player directly without connecting to the computer. before doing that check whether you have all the files as backup. after formatting, once again transfer all the songs, files you need. this solve your problem.   

Hello,
Just connect the player to the computer and open the player storage and delete the songs of your wish and add new ones.
Thank you, Smilemaker

To delete files directly from the Sansa player, follow these steps:
1. In playback mode, press the Submenu button.
2. Select Delete.
To delete music files using the computer, follow these steps:
1. Connect your Sansa to the computer.
2. Select Open device to view files using Windows Explorer on initial
connection.
3. Locate the folder where your files are stored.
NOTE: Music files are stored in the MUSIC folder. Voice recording files
are stored in RECORDING folders. Photos and Videos are stored at PHOTO
and VIDEOS folders, respectively.
4. Highlight and delete the desired files.

check the name of the file. right click on the file with your mouse and check the file name. sometimes the name will be the problem. if its something like videoname.TMP rename the file to videoname.MOV or videoname.AVI.

be sure to make a backup of the file before you make any changes.

good luck hope this solves your problem. if it doesn't work feel free to pm me

i try to dowload songs from my windiw media player and it remove songs from my 260 even when it is not full

I have had this problem for some time now and finally got through to tech support for Sansa and now have the solution:Worked for both 230 and 240.
Take out the battery in the Sansa player; Put on lock on back side of Sansa player; Connect Sansa to the computer, Once computer recognizes device cancel out of that media program; Go to my computer on desk top; Right click on recognized Sansa device; Click format; Click ok to delete files.

Well the SONGS folder might be hidden [happened to me]

Steps to see hidden folders:

-My computer
-Tools
-Folder options
-View
-Show hidden files and folders

With most MP3 players, some of the memory is used for system files and software. Just delete all the things you done use (i.e. pictures, playlists, Rhapsody Channels) and whatever space you have free is what you have to work with.

If you want more memory, I highly suggest a microSD card

Download powerdesk, the music file might be hidden and powerdesk will reveal it.

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).
