That depends on the time scales we're talking about. 30 years? Probably (and even then there are problems with abandoned/little-documented formats like Word 3.x). 300 years, and a historian will have a hard time decoding a digital file from the year 2019, even assuming the media is still intact. 3000 years and a nuclear war can make a weird shiny disc appear as a currency or a cult item for an archaeologist, not as a knowledge storage.
