File: Open...

Keystroke: Ctrl + o

Image shows the Open File dialog, which is actually titled "Select document file".

This opens the standard Windows File Open dialog window where you may select a file from your system or network.

If you select a file which did not originate in DBT, for example a Word file, you will see the following Import File dialog appear.  If the DBT can identify the type of file, it will be highlighted in the Import Filter Section.

Note that you can also Select the Template which you wish to use.  You may also set a default template if you wish. The "Set template as default," "Hide Template," and "Show Hidden Templates" controls work the same way as the corresponding controls in the File: New dialog.
