I'm not sure whether I'm asking on the right site, since all the other questions seem to be a lot more abstract and theoretical. If I should remove the question, please tell me.
Are all files on my computer an integer amount of bytes? That is, does every file on my computer consist of an amount of bits divisible by 8? Or are there files that are, for example, 300 bits (37 and a half byte), or 301 bits (37.625 bytes)?
Follow-up question: does this mean that every file can be 'read' using a program that reads ASCII encoded files? (Of course the output would be nonsense, but the program shouldn't notice any difficulties, right?)
