I, too, have used Anquet for walking before caching and also find it good for caching. There is a macro for exporting caches from GSAK by BandMandMandA and the latest version of anquet )6.2.2.0) now includes a GPX import which is the thing that has been missing up to now.
See this thread. and the macro is in the GSAK forum Macro Library
Thanks for the tip, it's greatly appreciated, even though it's given me a headache already
