Please explain what the advantage of this change is, why it's necessary, etc. and show screenshots with the change. You also need to revise the commit message (and perhaps PR subject) to reflect what the change is. Thanks.

Sorry Chewitt, I'm not a "pro" github user.
If used local downloaded nightly images (and not in the default "download" folder), the program always ("Select file" button) jumps to default folder. With these 3 rows, if a local file selected, the path is saved to "LibreELEC.USB-SD.Creator.ini" file.
Isn't a big advantage, you are free reject it if you want.

I'm not a pro either, which is why I like to understand what might be merged :)

You need to run git commit --amend to change the current commit message from "Update Creator.cpp" to something like "Add support for a persistent local 'Select File' path" .. then git push -f origin master to push the local commit to your GitHub account; which will update this PR.

Your change only saves directory but never reads it. Am I missing something?

[vlouis]

The value is used, look for "settings.value("preferred/savedir", getDefaultSaveDir())" at "creator.cpp" file.
I added to be saved at the manual file selection too ("Select file" button). It's useful for people like me, who use only previously downloaded nightly test images (and not to the default download folder).
