Think i tried that Stanman,and it was saying my usb location was not partitioned?? and would not save
Swap files will only save on partitions formatted in ext format (2, 3 & 4 iirc). So, if your usb is a fat or ntfs, it will not allow you to save there... Re-initialise your usb within your stb (you will LOSE everything on it, so backup anything you want to keep from it), and you should be fine...
1- In Swap manager did you use 'create' before trying to activate?
2- Windows doesn't read Ext by default; you'll have to find drivers for that.
