[gdal-dev] gdal.Warp error No space left on device.

[Deschamps, Benjamin (EC)]

Hi Even,

I misinterpreted the symptoms here, and simply replicated the (seemingly correct) out-of-space error on a different drive while trying to test.

Something else in my code is making gdal.Warp try to write out huge files...

Sorry for the noise.

Benjamin

No, but the .ige file is a side car file that is created next to the main .hfa file (.img is usually used) if the main file would be bigger to 2GB, so if you created the .hfa file on c:\, the .ige will also be on c:\
