Remote Access Drive Full

Hello guys 

I am trying to give a friend access to remoltey connect to my MyCloud to add in some files. However after setting everythinh up and getting to the drive over windows it detects it as being full. i feel like there is some form of quota but can not find the settings for it at all. 

Here are some screen shots

apologies for the order of the screenshots. 

That’s a Windows limitation with WebDAV access. It is the LOCAL drive that is full.
