Norton Ghost 15 Manage Back Up Destination Disk Size and Back Up Folders Questions

Hi,

 

I have two questions regarding Norton Ghost 15.

 

1. I have an external hard drive (FAT 32) , and the available size is 790GB, but Ghost only allows around 150GB for backup. I wonder if I can change the size that to be used for the back up?

 

2. When I create a folder to back up, it says" No Files Matched the backup criteria". In the folders, there are sub folders and files. I have selected  "subfolders". Could anyone let me know how to fix it ?

 

Many thanks!!!
