[gdal-dev] ESRI binary grids problem

[Sebastian E. Ovide]

thanks for that  Frank,

mounting a windows share folder with samba I can see the Overviews. Copying
the same files into a ext4 FS, the overviews are not detected. So I renamed
the .rrd and .aux files in undercapital (same name as the raster folders)
and now I can see the overview also under ext4.

about the errors:

ERROR 3: Attempt to read past EOF in
data/ie/rasters/ie_t02_q200//../info/arc.dir.
ERROR 4: Failed to open table .VAT

I have deleted (renamed) the info folder and now the errors are gone... just
wondering if I have lost any functionality...
