I have a question about custom facts and where they are stored.

I am reworking my  backup procedures and want to make sure everything is backed up. So far I have found the following locations for fact sets:

/ProgramFiles(X86)/FamilyHistorian/FactTypes

    Standard

    Extended Set

    Standardv1

    Standardv2

    Standardv3

    Standardv4

    Standardvr

Only by project so far

    Custom
    RootsMagic Import

Documents/familyHisorianProjects/FactSets

    DNA

    GedMatch

    Military2

My question is the location of the custom fact set when set for not project specific?
