Description

When using the "save as..." raster dialog together with the "create VRT" option it asks to select an output folder.

It happens that the dialog gives automatically the output VRT file the same name as the folder, and of the user tries to choose a different name it gets a "path does not exist" message.

Tagging as blocker as new features should work ok before releasing the new QGIS version.

this is not duplicate of #6952

NOTE
there is an issue also with output tif files as they are written without the extension

It was expected, that only one VRT will be written to a directory, it is feature, not bug. If VRT is checked, user can only select a directory. It may be reconsidered and changed to file if we are sure that it is better and really desired.

In any case, the dialog is not perfect, because it is difficult to define what should happen if a file was selected (including file extension) and then the format is changed. Automatically change extension? It may be problematic if user entered some strange name with dots.

I suggested in Essen to ask for the output file name when OK is clicked, but Tim did not like it because he is used to type output file name instead of to select it in a dialog and he does not want another popup window.

Note:
the following answer is strictly from a user point of view.

It was expected, that only one VRT will be written to a directory, it is feature, not bug. If VRT is checked, user can only select a directory. It may be reconsidered and changed to file if we are sure that it is better and really desired.

The user would expect another thing: in gdal tools when a VRT is created, the user chooses an input files/folder and then the output VRT file. The user would expect the same in the "save as..." raster dialog.

In any case, the dialog is not perfect, because it is difficult to define what should happen if a file was selected (including file extension) and then the format is changed. Automatically change extension? It may be problematic if user entered some strange name with dots.

if there are very important technical reasons then you may want to close this, otherwise this should be left open for future consideration (as bug, imho), because is really sub optimal.

I suggested in Essen to ask for the output file name when OK is clicked, but Tim did not like it because he is used to type output file name instead of to select it in a dialog and he does not want another popup window.

I can't see why should be opened a new pop-up. Right now it opens one asking for a folder, the same one should just allow write a output file name.

cheers!

There are no technical problems, there is just missing optimal solution proposal.

It opens the dialog if you click on browse button, but you can also type the output file name directly in save as dialog and that means one dialog less.

may be we would need a new category like "to be improved".

Another user wants to keep output raster in a separate directory and does not want to create new directory + select new file.

right, this is why I already downgraded the ticket. And now also made it a feature.
