I am not able to see the songs when I upload my MP3 with the computer, and it's occupying nearly 560MB space

MP3 players can only play music files in mp3 file format.You can download mp3 music files from the Internet toyour computer and then copy them to your MP3 player.For your CD collection, you need to convert your CDs tomp3 music files onto your computer or download them from the Internet and thencopy them to your MP3 player after you have connected the USB cable tothe MP3 player and the computer.
You can do this using Windows Media player and Rip the CDs - Media Player willcreate a MP3 music file for each music track.Click on this link for instruction on converting musicfiles to mp3 file format :- http://www.fixya.com/support/r5798418-creating_transferring_mp3_music_files

make sure that the songs that you uploading with your mp3 player is mp3 format, not wma or other, maybe your are loading a format that your player cant recognize.

Don't have the Mp3 player plugged in while you are deleting them. and if you don't have it plugged in then just make sure you have enough space to keep adding songs.

What you should try is backing up your unit, if there are songs from any other source on your player
other than the one main computer you use.

Determine whether the entire load is less than 2 GB and if so, then reformat your MP3 player to make
use of space from songs which, though deleted from your player, (such deletions only decapitate the
file header) still may occupy significant disk space which is at a premium on your player.

Totally reinstall your player and then load your music onto same, leaving some headroom (some portion
of 2 GB i.e. 100 to 500 MB) on your player to allow for streaming of your music, which will enhance your
enjoyment of same.

Plug your mp3 into the computer using your usb cable. Open windows explorer and click on drive "E". it might be different on different computers but a little playig around should find it. Then by trolling through it you should find all the files available on your mp3. Your problem was created by removing it from the computer without using the safety hardware removal. I still have not found a simple method to rectify this problem.

Hello,

Connect your sansa to the computer and then explore the drive and delete . also empty the recycle bin not to occupy space from your computer storage.

Same thing happened to me. I was using windows media player to sync my song and it says my player was using 260 mb of space even though it was formatted time after time. I simply loaded as many song as I could fit on the player. When I unplugged it and plugged it back in, windows media now showed that missing 260 mb of space as available. The only catch is that the song I had already uploaded on to the player were not shown on the sync list.
