从资源管理器中，获取被选择的文件的路径（及文件夹）的API

/* http://www.autohotkey.com/board/topic/60985-get-paths-of-selected-items-in-an-explorer-window/ Library for getting info from a specific explorer window (if window handle not specified, the currently active
window will be used).  Requires AHK_L or similar.  Works with the desktop.  Does not currently work with save
dialogs and such.

Explorer_GetSelected(hwnd="")   - paths of target window's selected items
Explorer_GetAll(hwnd="")        - paths of all items in the target window's folder
Explorer_GetPath(hwnd="")       - path of target window's folder

example:
F1::
path := Explorer_GetPath()
all := Explorer_GetAll()
sel := Explorer_GetSelected()
MsgBox % path
MsgBox % all
MsgBox % sel
return
