Coby 4 gb mp3

Your problem may be that your Coby MP601 does not support the file format of the file that you are trying to put on it.
They Coby MP 601 only accepts the following formats: Audio- MP3, WMA Video- MTV, MP4 Still Image (Pictures)- JPG
Check your file. If the three letters after the period do not match one of those letters above, the file format is not supported by this MP3 player. For example, an image title may be "IMG00658.JPG", but not "IMG00658.GIF".
To change file formats, there are hundreds of file converters that you can find on download.com for audio, video, and images. Once you have the correct file format, you should have no problem putting it on your Coby MP601 MP3 player.
Hope this helped.

Hello,

Transfers onto he MP815 can be done through exploring 'My Computer':
Music files must be copied into the Media folder of the player.
In this mode, the player shows as a removable disk in the computer folders.
Before disconnecting the player, always go through the safely remove hardware icon in the right corner below on the computer's screen.

When you're using a software program (e.g. Coby Media Manager or Windows Media Player) for transfers, use the help function in the software.
For Windows Media Player 11:
0. The player should be detected when you connect the USB cable.
1. Setup a library in WMP 11 [ Add to Library ], so the player knows the location of your music files.
2. Create playlist: put songs in a list
3. Sync the list onto the player
4. Wait until synchronizing has finished
Do not disconnect while sync is busy: a message appears when you're allowed to disconnect.

Thats probably because your music is protected Windows Media Audio files, try to sync an Mp3 file, this unit only reads MP3 or unprotected Windows Media Audio files.

Please install and use the “Coby Media Manager” software provided on the player.
CMM (Coby Media Manager) software is the easiest way to: Transfer (sync) media files to the player, Convert video and audio files to a format compatible with your player, Keep your player’s software up to date, Browse and play your media library on your computer.

ok first off there are a few ways to do this the most easy way i know is just using My Computer in windows and finding the icon that is your mp3 player or is listed as a usb storage device, open that up and look for a folder called music and if none exist then try just draging and dropping your music into that folder and see if that works. Next if that wont work try opening up windows media player, then connect your mp3 player, then goto the sync button at the top of the screen and see if your mp3 player is listed if it is then go back to the media library button and start draging your music that you want on there to the sync list on the side and after your done click sync. hope this helps

Ilo player must be synchronized, coping and pasting files is not enough:

1. Start Windows Media Player and select following menus: "File.", then choose "Add to Library." then the "Add" button. Then, look for the folder where your keep the mp3s to upload.
   
2. Plug the Ilo MP3 player into USB.
   
3. Click the "Sync" tab that you find at the top of Windows Media Player . You will find the Ilo MP3 player on the right side of Windows Media Player. If Ilo is not ther, then right-click on Sync tab and click "Refresh Devices."
   
4. Click "Library" then "Songs." on Windows Media Player . Highlight the son songs, and choose "Add to Sync List."
   
5. Click "Start Sync" button that will appear at the bottom right corner of Windows Media Player. The songs will then be uploaded to the Ilo MP3 player.
