I finished all of my very first game is PSX, so of course as a remembrance for a great victory, I saved the finished files.

One year had passed.....

Two years had passed......

Almost three years had past, I checked my files in my memory card (of course where else I would check my files?) Then I found out thet some of my files are gone.

Was it because I haven't opened or used it for a very long time?

Or was it my little sister playing around the PS w/o any CD inserted *
