How do you delete music off the archos 2 8...

To Delete Music or Files from your MP3

Hook up your mp3 player to your computer
Go to your desktop and double left click on "My Computer"
When it opens you will see listing that says "Devices with Removal Storage" your mp3 player should be listed there.
Right click on your mp3 player, and a window will open, right click on "Open" and now your files/songs should be visable.
Hold the left click down and drag it across all the files/songs that you do not want this will hightlight the files/songs you do not want, release, right click and then click on "Delete"
Now you mp3 player should be clear of the files/songs you do not want.
Good Luck,
I hope this helps
