how can i delete a file on my memory card ?

Hi, Save any data you need to save preferably to a pc or similar. Put the card back into the phone and FORMAT the card this will remove everything off of the card and return it to an unused condition, i.e. with nothing on it. Continue to use it from there. However, if the card is damaged, save all of the information you can, then throw it away and buy a new one. If you continue to use your present card, there is an increasing chance of the card losing all of the information stored within it. Please buy a quality card from a reputable company, you have a better guarantee and the card will last a lot longer with more reliability.
