Extend WebDAV file size limit

Windows applies an arbitrary file size limit of 50 Mb to WebDAV drives, despite natively supporting file sizes up to 4 Gb. To fix this change the registry key

1

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\FileSizeLimitInBytes

to 4294967295 or 0xffffffff and reboot or restart the WebClient Service.
