You can do something like this
1) open windows explorer (this can be achieved simply recording )
2) go to your folder by clicking treeview node selecting tree view
3)Name map your file using object spy This will look like ........(Aliases.explorer.Window("CabinetWClass", "C:\\Temp", 1).Window("ShellTabWindowClass", "C:\\Temp", 1).Window("DUIViewWndClassName", "", 1).UIAObject("Explorer_Pane").Window("CtrlNotifySink", "", 3).Window("SHELLDLL_DefView", "ShellView", 1).UIAObject("Items_View").UIAObject("soapUI_x32_4_5_1_exe")) here I have got soapUI exe in my C:\temp folder.
in that object you can click anywhere (eg hight/2 and widhth/2)
4) Drag and drop using above mapped object and it's points to your app click here for more
this is high level steps and please try and ask any practical problems.
