> But you're selecting the file in a file manager and then dragging it into your "file selector". That whole dialogue then becomes completely redundant because you might as well just drag that file into the application window without having to click "open".
Sometimes. Others the dialog is how you set things like the format of the file or some import options. Or you need a multiple selection and dropping a bunch of files just opens them separately. Sometimes you can input a regex and you just need to quickly go to the right directory. Sometimes you need to select a file to import it into another document and not open it. It is also damn convenient to just drop the folder where you want a new file to be in a “save as” dialog without having to navigate from dog knows where. There are plenty of use cases.
What is redundant is a file manager in an import dialog. There is a full blown file manager that’s always going to be better just a click away.
> If you drag the file into the text area it will work as you wish.
In theory, yes. In practice it’s hit and miss as developers don’t seem to care about using native widgets (that, and the fact that native widgets have vastly different capabilities on Windows thanks to years of cruft they cannot remove).
[edit] sorry if it sounded harsh; I have nothing against you. It’s just that the file selection dialogs are a particular pain point on Windows and Linux.
