This is a standard Windows® save dialog box for saving files of various types. Choose a location using the Save In listbox or Up One Level button, choose file type and file name, then press OK (or Open) to save your file.

You can also use the dialog to toggle the List and Details buttons for different views of the contents of the current directory, change names of files and directories, and right-click on any folder or file for Properties and other options. The Create New Folder button creates a new subdirectory of the current directory.
