I have some problem with my flash memory. Recently, I took some pictures from my camera. I sent them to my flash disk and then I deleted them from my camera memory. Unfortunately, I met a problem when I wanted to see my pictures. They can not be viewed. I don't really understand why, but some explain me that the matter was my key. Bizarely, The capacity of my pictures are good enough for me to think they ca be availaible. That's is why I didn't delete them yet. Please help me to recover those pictures. Thanks in advance.
