Whenever i delete files from my 2gig sd card it keep reappear, I have even tried formatting the card but the file are still there. I have even tried adding file to the card after deleting the original files but to no luck since when i check the card the original files come back and the new ones are deleted.

The card was give to me by someone who had it in his phone before but told me that he formatted it before.

I have noticed that there is a hidden system file on the card which i assume is what causing the problem.

So can anybody tell me what else can i do to delete the files or is it that the card is corrupt?
