[gdal-dev] Check of sibling files when opening an image file

[Armin Burger]

Hi all

When gdal opens a file, it checks for various sibling files, like *.MTL,
*.aux.xml, *.RPC, etc (this is the case when the full directory scanning
is deactivated). This can be ~30 stat or open requests when opening a
single image file. Is there a way to define the file types that gdal
checks for their existence, thus allowing to reduce this to the pure
minimum, like *.ovr files only? Is this check driver dependent?

Thanks in advance for any hints
Armin
