Jukka,
Hmm, not the most appropriate error report. If you file a ticket, I
or Chaitanya can try and improve this.
Dbf seems not to have such size limit because it grew up till 32
gigabytes.
I will try MapInfo tab before I believe that it is just best to keep the
1000
shapefiles or upload them all to PostGIS.
The .shp format explicitly uses 32bit offsets and so cannot
practically go over 8GB (it actually uses 32bit offsets to
16bit words) and I would not trust compatability over 4GB.
The dbf format does not have any offsets in it, so it can be
arbitrarily large, and recently shapelib and GDAL/OGR were updated
to handle this.
Best regards,
