I agree with MLB's comment that "it looks on the surface like you are simply using the wrong tool to manage your data. File management is the domain of the PC at the least and a server at the best. Nearly everyone I know manages jobs by name and date.
" and woder why you'd need all those points in your data collector (DC).
Do you actually manage your data in the office, as per MLB?
Or does your office survey/CAD software not handle the "large" files adequately? If that's the case, you need better survey/CAD software. Even free software like Copan
can easily handle much larger files than your 6600 point example.
Eliminate points? No! Keep all your data in your office, somehow, and, when needed, extract copies of just the control points (or whatever you really need) from the office system, to place on the DC, for each trip back to the field.
