I suspect this may be more of a concept / theory question, but, I haven't been able to wrap my brain around what exactly a binary file is.
I've read links such as the below:
But, the piece of the puzzle that's confusing me, is that ALL files are stored as 1's and 0's on a hard-disk, or, in RAM, etc. (i.e. there's no physical engraving of the hex characters "6F" onto a disk platter for example; it's still a binary format that the data is stored in).
So, if all files are stored as binary, then, presumably it's an operating-system, (& filesystem) concept to refer to something as "binary" file?
