Hi Frank & List I tested the program below but it does not out put the .tab or .mif/.mid with the coordinate system.  It is always non-earth.  Could you please check it against your gdal/ogr installation to see if something went  wrong during my compilation of gdal 1.6.2? Thanks a lot,

Perhaps, although not yet supported by GDAL because publication of the format is not due until 2010, the new ESRI File geodatabase might be something to explore. This is limited only be any operating system restrictions on size and appears to be replacing the shapefile in due course. However,

Hi, Maybe I need to clarify a bit my aim. This is huge dataset with hundreds of layers and we do not use actively all of them. The layers we need we will insert to Oracle database but it is a managed, hosted production system and it is far too expensive to use it as a backyard storage shed. W

Hi, Interesting topic ! The most efficient way is the one which will fit your needs the best. Forget the OneShape idea, but I think you can either have a database approach (either PostGIS or Oracle) or a file approach (your thousands of shapefiles). It depends on what you have to do with data and
