How do you successfully save a custom OOB?

Thanks, sadly I've tried that unsuccessfully.

Does the name of the folder you are using to hold a custom .spf OOB file matter, ie does it have to be 'Custom Folder' or could it be 'Custom Romanian OOB Folder'?

Now that I'm sure the file name would have to be spob16.spf, I'll experiment some more to see if I can get it.

BTB, does it have to be the exact same name, ie spob16.spf, or could it perhaps be in the same format, ie spob46.spf?

I will get this figured out, esp with some pointers from someone who knows how.
