Large File Transfers

Hi Guys

Having a little trouble here. im trying to transfer a file that 500GB across to my 8TB EX2 Ultra but everytime i try it says that the file size is too large when i still have 7.8TB available. is there something in the settings im missing??

It seems the problem is not space but the method.

What tool are you using to transfer this file?
Where are you trying to transfer it from?
Do you have additional 500GB or more on the source drive?
Are you able to transfer part of the file or it fails immediately?
If it doesn’t, how much of the file are you able to transfer?

it started working by itself after a while of waiting. no idea what happened there
