Can see buffalo NAS but folders are empty

[beardypete]

Hi,

I can see my Buffalo Link Station's root folders using File Manager HD to browse the local network on my Nexus 7 (Android 4.2.2), but when I open any of those folders I see a '(directory is empty)' message. Using the same file browser on my phone running Android 4.1.2, I can access all the folder contents without any problems. The Buffalo is accessible from PCs too so I don't think it's a permissions issue - what else could it be?

Thanks in advance,
Pete
