Hi - I think Mike wrote that his speculation on the number of file formats is a distraction and I agree.
I would, in fact dispute his claim and say that are likely to be millions of file formats. Especially this is true since some of these file formats predate electronic computers by over 100 years. For example - https://en.wikipedia.org/wiki/Jacquard_loom <https://en.wikipedia.org/wiki/Jacquard_loom> (I am assuming that you could build a scanner and digitize.) https://en.wikipedia.org/wiki/Punched_card <https://en.wikipedia.org/wiki/Punched_card> (unfortunately much of the 1890 US census was burned in a warehouse fire.)
