Microsoft confirms weird Word bug that deletes files if you name them incorrectly
Microsoft has acknowledged a peculiar issue with Word that can cause files to be deleted immediately after they are saved. Users of the word processor are being warned to avoid naming their files in a certain way to avoid data loss while the company investigates the problem.
While having to meet specific criteria when saving files is not unusual, using an illegal name would usually simply result in an error message and a prompt to choose a different name. With this bug, however, the file appears to be saved when in reality it has been deleted.
