Used to retrieve various documents on old floppy disks. Under W7 and XP, faith, any concern for recognition for one, you put the USB socket, it is recognizable, it sinstalle the disk is inserted it makes little noise exudes an (brzz brzz) (who remembers the sound of the first modems nostalgia ....) and "up" on the office alone; 25-28 on floppy disks, there is only one that has not worked. At that price, it's a gift. I never thought it as easy and obvious and time saved later. I made a folder with old documents and I gave them up to date and in another format, another folder ... I'm an old lady, if I can do it, you can do it! (More one feels super proud after).
