Hi Kai, I believe an MSI file is based on Microsoft's compound file format, which is basically a file system within a file.
A compound file has a default sector size of I think 512 bytes, so you will notice that your MSI file size is always a multiple of this sector size. I hope this information helps.

I was quite surprised to see that all three are absolutely identical in byte size - there must be some padding of sorts going on. Is that a valid assessment, and if so, why is that?
