The familiar warning box when reformatting a disk in Windows, created as a temporary solution 30 years ago, is still in use today. Dave Plummer, a former programmer at Microsoft, recently revealed the surprising story.

Despite many overhauls that have gone through the Windows user interface, the format window has remained the same since the days of Windows NT. And if you were wondering why the format volume in FAT is limited to 32 gigabytes, Plummer has something to do with this as well.
