What happens when a user tries to open a file named "hfa:example_file.img" the current way when there is also a file name "example_file.img"?<br><br>What if we try to reorder the driver list according to the file extension?<br>

I believe that is because it is hard to know if HFA:test.tif was really<br>
something other than a request for the HFA driver. It could actually<br>
be a file named "HFA:test.tif" or it could be that another driver happens<br>
to use the HFA: prefix to mean something. I believe this is an<br>
effort to avoid failure in these cases.<br>

Um... the best I can say then is -0 in the hope that we can find a better delimiter or syntax. Unfortunately I just can't come up with a better option at the moment.<div class="im"><br>

I'm not convinced that this is necessary. I have had a hope for<br>
some time to provide a standard way of binding up open options,<br>
including the driver name, for OGR as demonstrated by a<br>
request like:<br>
<br>
@driver=ingres,dbname=test<br>
<br>

Unfortunately "@driver=ingres,dbname=test.<u></u>tif" is also a valid filename, so we'd have the same problem as with "HFA:test.tif" above.<br>
<br>
I also think it is important to be consistent between GDAL and OGR for something like this.<br>
<br>
Once again, I'm not trying to kill the idea, just pointing the flaws in the hope that the someone in the group will find a more predictable mechanism.<div class="im"><br>
