I prefer using the NOAA raster BSBs to vector formats for coastal US stuff - at least until they go away not long from now.

NOAA offers the ability to just download as BSBs at once, which is great because I don't have to change things whether we're racing on the East or West coasts, or the Great Lakes.

All of the BSBs is over 1 GB of data and a zillion files.  I'm wondering:  will I see a performance hit in Expedition if there's as zillion BSBs in the data folder?  Could it slow down zooming/panning, etc.?  Is there any other benefit to only having the charts I know I need in the folder?

Thanks!
