How it works
Why does a file show 1.05 MB in one place and 1 MB in another? Two conventions coexist: decimal units (1 MB = 1,000,000 bytes, used by macOS, disk makers and most websites) and binary units (1 MiB = 1,048,576 bytes, used by Windows, which still labels them “MB”). KadiTools shows both, plus the exact byte count.
