DELETING VIDEOS FROM MP3

Below are the instructions. I hope I've made them clear enough!
Make sure your device is under MSC instead of MTP...To do that go under Menu, settings and then usb mode...
--

Step 1
Open up Windows Explorer: Start > Programs > Accessories > Windows Explorer

Step 2
On the right of Windows Explorer, click on My Computer

Step 3
You should see two devices after your CDROM drive. One will be SANSA E260R and the other will be Sansa e200R Rhapsody. Chose the one on the top; the one that doesn't say Rhapsody. It may say E250R, E260R, E270R, or E280R depending on which model you have.

Step 4
Once you're viewing the device, you'll see the folders: PHOTO and VIDEO. These are the folders that contain your photos and videos. For videos, you can simply remove the video you want to delete - it will completely remove it.

I hope that helps
