This is such a convenient feature that I use constantly on my Macs and miss every time I am using my windows workstation. Is there a setting or plugin that will enable this? I always though this was an Adobe feature, not an OSX feature but I have not been able to find any way to enable this in Windows.
It's a Mac feature, and Microsoft deliberately designed Windows so it doesn't work. You're supposed to drag and hold over the toolbar icon, and wait for the app to open, then continue the drag to the app. Safest place to drop is the title bar, doesn't always work.
Both Mac and Windows support dragging a file to a desktop icon.
Thank you for this information. This procedure works if Photoshop is already open, but not to start the program like it does on OSX. The title bar tidbit is quite useful though as it seems to work the best as long as PS is already running.
It's frustrating that dragging to a desktop icon works but not the task bar as the task bar is always visible, unlike the desktop.
