@zwb124 Are you using Win 11 Arm Preview version? It has a file transfer limitation. You can edit the registry like below.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters] "FileSizeLimitInBytes"=dword:ffffffff

@aisobe Is there a performance reason on why the default is not larger ? It worked like a charm

What if the file size is bigger than 4~5 GB? Because it seems that the maximum limit allowed is 3.99 GB or so
