Can I add favorites from the command-line or a batch?
You do it with the QAP executable companion QAPmessenger.exe installed in the QAP application folder. This utility is used to send commands to QAP from the Windows Explorer Context menus. But you can also use it this utility to add QAP favorites from the command line, a batch file, a Windows shortcut, etc.
Enter one of the following lines at the command prompt, in a .BAT file line or in the Target field in a Windows shortcut. Replace C:\Program Files\Quick Access Popup\QAPmessenger.exe with the current path and filename of QAPmessenger in your setup.
The two first lines add folders and the other ones add files. The ones with "Express" add favorites with default values without showing the dialog box (be cautious if you use them in a batch loop).
"C:\Program Files\Quick Access Popup\QAPmessenger.exe" AddFolder "C:\FolderPath" "C:\Program Files\Quick Access Popup\QAPmessenger.exe" AddFolderXpress "C:\FolderPath" "C:\Program Files\Quick Access Popup\QAPmessenger.exe" AddFile "C:\Folder\FilePath.ext" "C:\Program Files\Quick Access Popup\QAPmessenger.exe" AddFileXpress "C:\Folder\FilePath.ext"
