Open a File with Notepad

Open With window with Notepad selected.

Many of these formats are text files, they just have a special name.

By default, Windows doesn’t know how to open *.gci files. Here’s how you tell it:

  1. Right-click your nyc.gci file to get the context menu.
  2. Click Open With and one of these things will happen:
    • If a window appears with two options, select Choose a program from the list.
    • If it opens a submenu and Notepad is an entry, click that.
    • If it opens a submenu but Notepad is not there, click Choose Program at the bottom.
  3. You should now see an Open With window.
  4. Find the entry for Notepad in this list and select it.
  5. Tick the box saying Always use the selected program to open this kind of file.
  6. Click the OK button.

The file will now open with Notepad! Next time, you can double-click the file and it will open in Notepad straight away.

Change from Notepad to Something Else

Sometimes you don’t want to use Notepad. If the program you want is in the Open With list, you can select it just like you selected Notepad. The instructions are the same.

For programs which are not in the list:

  1. Go to the Open With list, just like before.
  2. Double-check the program is not in the list. Maybe you just missed it!
  3. Click the Browse button.
  4. Find the *.exe file for the editor you want to use.
  5. Select the file and click Open.
  6. The program should now appear in the list and be selected.
  7. Tick the box saying Always use the selected program to open this kind of file.
  8. Click the OK button.

The file will now be opened using the editor you chose. Now the file will open in this editor.

To change the editor again, just repeat these steps but choose a different program.
