There should be no problem assembling more than 32 files in a VRT while keeping the number of files opened simultaneously below a certain threshold. By default, it is set to 100. But you can change it by setting the GDAL_MAX_DATASET_POOL_SIZE configuration option/environment variable to another value, e.g. 30 in your case. > > Jose _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
