PAF newcomer

hello everybody!

im a frequent visitor here.
all of my apps. are either PAF, NSIS, but are all portable except for the few that need to be installed.

i have been using NSIS to make my portable apps. but decided to switch to PAF because of John @ PortableFreeware.com.

I have successfully built a few apps already.. but i have a few nagging questions i hope can be clarified here

1. If the application stores it's settings in the registry:
- do i have to use [FileMove] to back it up in addition to [registry]activate=true? or is setting the registry key to be portabilized enough?

i.e. i use [FileMove] if the app stores it's settings in an .ini file incase of future updates.

2. What if an application leaves files on the host PC? i have found [DirectoriesCleanupIfEmpty] for cleaning up directories.. but nothing for files? or am i supposed to move them to TEMP, then clean up TEMP directory?

Thank you
