Hello,
Go to cobyusa.com for Coby support.
Specific downloads for the MP610 can be reached if you enter MP610 in the Product Search bar.
When you need Coby Media Manager go to the link "fix for MP822" on the support site cobyusa.com: the fix is the Media Manager from Coby, it can be installed for Windows as well as for Mac.

When using other software programs like Windows Media Player 11 or iTunes, look in the help function or internet site for the used program.
For transfers mainly go through next steps:
0. First install and update the software you will use for transfers
1. Running the software program, the player can be detected in the used software program when connecting the USB cable
2. Setup the library in the used program: the location of the media files must be marked to have access to the data
3. Create a playlist: for example put songs in a list
4. Transfer the playlist onto the player: synchronize the list
5. Wait until the data finished synchronizing; wait for the message you're allowed to disconnect, after that you can take out the USB cable
