I was wondering that too and hoped you would known the answer ;-) There's perhaps a Windows API for that... ? FWIK SMB filenames are in the form "servershared_folderxxxx" , but it can be mounted on a drive, so it becomes "X:shared_folderxxxx". Perhaps there's a way of resolving this to the original name ? But I'm not sure it is really needed either. Perhaps the theoretical performance loss is neglectable in practice. I'm just throwing thoughts. _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
