Update: Denise thank you; I have made good use of the MobileCacheTool taking the MapCache local database on the Trimble to shapefiles and images. I am doing so again now to solve an issue with Syncing, it would still be useful to be able to 'reset' the synchronization state back so that it could be tried again in the cases where the sync appears to work and finishes successfully yet data is not added to the database, One can not retry as some 'bit' gets set which prevents trying again unless you 'touch' each record (add comment etc) and try again or export with the previously mentioned tool.
