What is max filename character length

The filename length related to folder path length, according from Microsoft https://msdn.microsoft.com/en-us/library/aa365247.aspx the total length is 260 character, inclued with IP and folder path.

Example:
NAS IP is "172.16.10.10"
Folder at "USBHDD"
=> \\172.16.10.10\USBHDD\ => 22 character

Thus 260-22=238 max filename length will be 238 character, included dot & sub-filename.

The max filename length is 238 character:
