today I cleaned the drawers and found an old USB floppy drive and disk, surprisingly it still works, the files were first written to the floppy disk in early 2000, among 30 files in total, 5 of them are not readable, 25 of them are good and copied correctly. They are all pictures. I suddenly found that after decades, technology has changed and advanced a lot, but the kind of pictures and videos I am watching today doesn't have any change....
