How can I edit the file QuickAccessPopup.ini?
Normally, the QAP settings can be modified using the QAP Settings and Options window and you don't need to edit the .ini file containing your favorites and your preferred configuration.
For some specific operation, you may need to edit this file named QuickAccessPopup.ini that can be found in the QAP working directory. You can open this file using any text editor.
But the easiest way to open the settings file is to use the QAP system menu: right-click on the QAP icon in the Notification zone select Edit QuickAccessPopup.ini.
The file will be open in your default text editor for ini files (Notepad if you did not change it in Windows).
