try this site "downloads .cnet.com"

it is not appering in my copmuters but it is charging.

If you mean you can't put the MP3 files you downloaded onto the player, then you simply need to plug the player into a USB port on your computer -- either directly into the port (for some player models) or via an extension cable.
Once you've done so, the computer will "recognize" the player as a new disk drive, and assign a drive letter to it. Your computer will normally inform you via a pop-up, that it found new hardware.

Now just use Windows Explorer to drag and drop the mp3 files onto the new drive. This loads the files onto the player. Once the transfer is complete you can unplug the player, and it's ready to go.

go to settings on player then usb change from auto detect to msc worked for me.

Yes, formatting your MP3 Player will erase everything on it other then the required system files.

If the MP3 Player is USB Compatible, plug the USB into the MP3 Player usb port, then plug the other end of the USB into your computer (provided your computer has a usb port). Depending on if the MP3 player needs software to put music on it, it should be easy.
Allow the MP3 Player 1 minute to fully load onto your computer.

Goto:

1) My Computer
2) Find your MP3 Player, should be something like F: Drive or MP3 Player (depends on the kind).
3) Double click on the icon of your mp3 player.
4) If there is music or anything in there, create a folder on your desktop or where ever you wish to move the music.
5) Highlight every song or anything, and right click drag it into the folder you have just made.
6) Make sure no songs are on the mp3 player.
7) Unplug it, check for songs, and if successful, you should have all your songs off your MP3 player and onto your computer! Double check, then you can format it or do what ever you wish!

Hope I helped :-)

THERE is sometimes some restrictions on the format you can inject in your player, (sometimes no wma, only mp3, and for sure, basicly) 128bps

the best way for that is to read your manual.
