Is a file a string of zeros and ones? Is a computer file just a string of zeroes and ones? If so, can it start with zeroes?
I have not been able to find an answer, surprisingly.
Yes the File has a binary representation and it can start with a leading zero.
To verify this open any file from your computer with an hex editor and modify the leading hex to 00.
You would most likely be unable to open the file, because you damage the signature but it still can be considered a valid file.
