File too large to copy

WD Legacy Products My Book Live
1

I did a System image of my W8.1 and the file size is 135Gb.  I want to store this on my NAS which has 1.85T free but when I try and copy it it says 

‘folder’ is too large for the destination file system.

Any ideas?

Ok, got it to work.  If I access it on the network via:

Network/MYBOOKLIVE/myfolder

it fails

If its

Network/192.168.0.200/myfolder

it works!

Odd, but who cares!
