A File Manager extension sends an FM_REFRESH_WINDOWS message to cause File Manager to repaint either its active window or all of its windows.
FM_REFRESH_WINDOWS
wParam = (WPARAM) (BOOL) fRepaint; // repaint flag
lParam = 0; // not used, must be zero
Parameters
fRepaint
Value of wParam. Specifies whether File Manager repaints its active window or all of its windows. If this parameter is TRUE, File Manager repaints all of its windows. Otherwise, File Manager repaints only its active window.
Return Values
This message does not return a meaningful value.
Remarks
File-system changes caused by an extension are automatically detected by File Manager. An extension should use this message only in situations where drive connections are made or canceled.
