Keith, please do not confuse self and people.

In the Valentina kernel exists 4 string constants.
ValentinaSetExtensions() just change values of this constants. Nothing more.

Assume you set 

    ValentinaSetExtensions "vtc", "dat, "blb", "ind"

Now, if you do 
    db.Create( "dbname.vtc" )

You must get files:

    dbname.vtc   
    dbname.dat
    dbname.blb
    dbname.ind


-----
If you do 
    db.Create( "dbname" )

You must get files:

    dbname
    dbname.dat
    dbname.blb
    dbname.ind

-----
If you do 
    db.Create( "dbname.vdb" )

You must get files:

    dbname.vdb
    dbname.vdb.dat
    dbname.vdb.blb
    dbname.vdb.ind


This is where must be effect of ValentinaSetExtensions() call.
"vdb" -- now is not considered as extension, because you have told above
that extension must be "vtc". As result 'dbname.vdb' is considered as SINGLE
name.

This is a logic I want provide.
You see any problems here ?

Question to you Keith, have you made before Create()
Call as 

    ValentinaSetExtensions "dbq", "dat, "blb", "ind"

    db.Create( "mydb.dbq" )

???? 

Check this point, if you have made this call, then only I need fix bug which
you describe.
