Hi Matthew, I am Henry and I'd like to offer some insight into your issue.
This is expected behavior starting with Windows 11 (22H2+) — the new WinUI 3 File Explorer no longer allows dragging files into the address bar to insert the path.
The official alternatives are:
- Keyboard Shortcut – Copy as Path
- Select the file.
- Press Ctrl + Shift + C.
- The full file path is copied to clipboard and can be pasted into Explorer, command line, or any dialog.
- Mouse Method – Context Menu
- Right-click the file.
- Choose Copy as path. (On some builds, hold Shift + Right-Click to see the option).
These are the supported replacements for the removed drag-and-drop behavior.
