An even better way is to file *across* the holes, cutting the brass body

Even better is to do both. Removing the plating inside the hole will
promote the flow of solder across the junction of connector body to
shield, which is what we want.

Sorry, I cannot have explained that clearly enough.

If you do what I suggested, there is no point in removing the plating from
the inside wall of the hole first, because you're going to file all of
that metal away.

Keep filing until the inside wall is completely gone, and the hole is
surrounded by a sharp edge that tapers to zero. At that point, stop
filing - it's ready for soldering.

Let me see if I have this straight. You are filing on the round part of the
connector barrel where it has the 2, 3, or 4 holes for soldering to the
shield. You use a narrow flat file, and file just short of the point where
the holes would become oblong?
