Please login to admin web interface, select [Network Service >Samba / CIFS], please Disable the Optimize Block Size function, default is Enable.

As enable the function, the block size is calculated by 262144, after disable the function, the block size is calculated by 4096.

After disable the function, please reboot the NAS. Finally the size on disk of NAS will exactly as same as Windows Explorer.
