Under Windows the settings are in the registry, under Linux they are in .xml files. It is probably possible to move settings from Desktop FBReader to the PocketBook, but the latter seems to be using a relatively old version of FBReader (based on the MOBI images bug still being present). At one time all the settings were numbers but now they can be names which are more human readable.
