If Winamp suddenly stopped opening, playing, enqueuing shortcuts to audio folders
Putting Winamp to the “Send To” context menu
To do this, copy the Winamp executable (normally at c:\program files\winamp), and navigate to the “Send To” folder (normally at c:\Users\YOUR USER NAME\AppData\Roaming\Microsoft\Windows\SendTo). When you are in this folder, right click on an empty space of the folder and select the option “Paste Shortcut“.
Now you have created a shortcut to the Winamp executable right in the Send To folder of Windows. Next time you need to play in Winamp an audio folder by right clicking on a shortcut to that folder, do not choose the Winamp’s Play context menu, but go to “Send To” and use this menu to send your files to Winamp.
To do the same for Enqueuing your files to Winamp, placing them at the bottom of the playlist, just create in the Send To folder another shortcut to the Winamp executable, right click on it to open its properties and replace the target with:
"C:\Program Files\Winamp\winamp.exe" /ADD "%1"
You can change the path to Winamp according to your specific system configuration, but leave the quotes in their place, they are needed. Don’t forget to give a different name to this shortcut, to know when you are going to play or enqueue a folder.
