can not format micro sd

Hi all

i have 64gb sandisk ultra micro sd xc1… using it for 3 years with my Note4.

For a few days i can see the all files in it ,but i can not delete any file or format the card.

windows says formatting can not be finished.

i tried so many ways for formatting .special programs , by cmd command made diskpart and clean  also…

the interesting thing is i can see all my files,photos etc…i can open them ,but i cant delete,

Also i tried to format with my phone…

The system of the card is exfat .

waiting your helps.
