Can I change folders in file dialog boxes (Open, Save As, etc.)?
Yes, the main QAP triggers (middle mouse button or Windows+W) can change folders in all software that use the standard Windows file dialog boxes (Open, Save As, etc.). Most software do.
However, this feature must be enabled in Options (first tab General, first option of left column).
If you enable this option, you understand that this feature is reserved to "file dialog boxes" (Open, Save As, etc.). If you use it in other types of dialog box, for example a Preferences dialog box, trying to change folder in this dialog box could modify and save values in the dialog box without any notification.
In order to enable Change folders in dialog box, you must confirm in the QAP Options that you understand the consequence of misusing the change folder feature in "non-file dialog boxes" and that you will only use it the proper dialog boxes.
