Files take place over contiguous blocks of memory. In those blocks are a bunch of zeros and ones. For Apple File System, the minimum block size is 4KB. So I'd be storing 7 bytes in a 4KB space. The fact the file exists and its metadata (its name, extension, creation date, update date, permissions, and the location of the block where it exists) is stored in a B-Tree by MacOS. **** # More ## Source - self - conversation with Gemini
