Map files

Does anyone know or can explain what the difference is between the poi.dat and the crpoi.dat files are? Just curious is all.

[MrDJ]

The crpoi files appear to contain (or allow) the address details to be viewed in POI.

crpoi = Compressed Rich Point Of Interest
To see the "rich" detail select Navigate to ... Point of Interest ... POI near you ... select one of the built in categories ... select a POI ... If there is rich detail for that poi then a Details button appears under the phone number on the right of the screen. Click the Details button to see the the rich detail. This is often an address, web site url and email address but is technically capable of including any text and also pictures.

crpoi.dat contains only the "rich" detail.

poi.dat contains the POI and for some POIs also has a "pointer" to the entry in crpoi.dat.

If you delete poi.dat you will delete all of tomtom's built in POIs. The crpoi.dat file will then have no useful purpose.

If you delete crpoi.dat you don't delete any POIs but you do delete the "rich" detail for all of the built in POIs. There have been reports that this can cause problems (hanging, rebooting) if you press the "Details" button for a POI that has a pointer in poi.dat. I've not tried it myself.
