There will only ever be one address in the tx file -there is one text file per address.

The paging files could also be broken by crashes, it's no different.

Not a good idea - there's no need to do this especially if the address is flipping between paging and not, you will get a lot of thrashing.

The text file will only ever be created once - when a destination starts paging.
