Vista - Deleting Folder on SD Card

All of a sudden I cannot delete files off any SD card I put in my Compaq
Presario F700. Delete isn't even an option when I right click on the file.
This happens with the card from my digital camera and also with the small
card in my cell phone which I have to insert into a SD holder. I know I must
have clicked something that was a no no. Is there any way to fix this.

THANKS!!!

Formatting a card in-camera is best practice and it should be done *every*
time the card is inserted into the camera. Any decent DSLR will have a key
combination to do it so you don’t have to dig through the menus.
If you delete some photos or even all the photos from the card using a
computer, the file structure on the card can be compromised when used back
in the camera and may affect the writing of new images.

I have never formated the card. UGH! When I try to move or delete files, it
says that it is write protected. How can I change this? I've never had a
problem before. Thanks for your help!

You didn't accidentally move the little slide switch on the card to the

Never having formatted the card could be the cause of your problem. Most if
not all cameras strongly recommend you format the card in-camera BEFORE
using it.
