How to open windows explorer when I click a button?
Well in case you need to select some particular file in explorer I have the following function which I use
procedure SelectFileInExplorer(const Fn: string);begin ShellExecute(Application.Handle, 'open', 'explorer.exe', PChar('/select,"' + Fn+'"'), nil, SW_NORMAL);end;and you can call it :
SelectFileInExplorer('C:\Windows\notepad.exe');EDIT: As mentioned ShellAPI must be added to your uses list
Building on what Mason Wheeler said: you can also pass in a directory as an argument, to get the window to open to a non-default location:
uses ShellAPI;... ShellExecute(Application.Handle, nil, 'explorer.exe', PChar('c:\'), //wherever you want the window to open to nil, SW_NORMAL //see other possibilities by ctrl+clicking on SW_NORMAL );
