When you download the client again, it is a 22G file.

This 22G is converted by the operator, and the operator is calculated according to the decimal method.

That is, the conversion of the operator is1000b =1kb1000kb =1MB1000 MB =1g22g = 2200000000 bytes.

The computer conversion method is binary.

Simply put, the computer conversion ratio is1024b =1kb1024kb =1MB1024mb =1g.

Therefore, the 22G provided by the operator is agreed on the 20G of the computer.

So it's not that the client is small, but that different algorithms between computers and humans produce different results.
