I have a .bkf file on a compressed drive:

View Tiles says the size is: 715,288 KB

Properties says the sizes are:
Size: 698 MB (732,454,912 bytes)
Size on disk: 481 MB (504,553,472 bytes)

I could see why 2 different sizes would be listed: compressed (size on
disk) and uncompressed (size) ... but _three_ different sizes?

Which size is correct? How much space is the file _really_taking?

732,454,912 bytes = 715,288 KB so both of those sizes are the same.
Like wise 715,288 KB = 698.5234375 MB. So those are all consistent.
Remember that 1 KB is made of 1024 bytes, not 1000 bytes.

732,454,912 bytes / 1024 = 715,288Kb
732,454,912 bytes / (1024*1024) = 698.5234375 Mb

So the "properties" filesize is truncating-off the decimal-Mb.

504,553,472 bytes /1024 = 492,728Kb
504,553,472 bytes /(1024*1024) = 481.1796875 Mb is physically occupied
