Hi,

the difference between the two numbers comes from how the bytes are counted. The bigger number (e.g. 4.7) uses powers of 10, whereas the smaller number (4,37) uses powers of 2.

The former is called Gigabyte, the latter Gibibyte (for binary gigabyte). In essence, 4.7 GB (1000 * 1000 * 1000) equals 4,37 GiB (1024 * 1024 * 1024). Different number, but actually the same amount of bytes. A big cause for this confusion is that Windows shows amounts based on binary calculation, but writes out the ten-based unit names, i.e. it says "4,37 GB", but it should say "4.37 GiB".

There is also a difference between lowercase and uppercase b. Lowercase denotes bits, whereas uppercase stands for bytes (easy to remember: the small letter means the smaller unit).

It's always a joy to listen to your calm speech. Greetings.
