virtualbox.org

This problem started Sunday I think
Im using 2003 server (32 bit) as host. I have expandable 40GB virtual drive on virtual box. The host has a 20GB drive but only contains fresh install of 2003 with 9GB free and VirtualBox files/machines are stored on NAS hosted on 2008 server with about 400GB free.
I do have read/write access and have confirmed by copying random files over then deleting them.

What is the file system on the share? Can you save files larger than 4 GB on it? FAT can't handle files larger than 4 GB.

I see you posted in the Linux Hosts too. That is not what you should do. I'm locking this one. Crossposting is not allowed here. See the Forum Posting Guide for that.
