DB3 Files

[FACTflights]

In the DATA folder,my system has 7 NavData.db3 files dating from November 2013.  Can some of these files be deleted?

John,

One db.3 file remains from each Navdata update to a maximum of ten files when the oldest one is replaced, they do no harm, slow nothing down but they can all safely be deleted apart from the latest one which is the one the system is using.
