Most often, the reason you can’t open an attachment is because your computer does not have a software program that can open that type of file or, your computer doesn’t know which program to use to open that type of file. Save the file to your desktop then follow the steps below.

Identify the Attached File Type. Usually the file name of an attachment indicates the type of file it is. For example, a file named A.GIF has a file extension of GIF which indicates that it is probably a GIF image file. Knowing the type of file allows you to select an appropriate application program to open the file in.

Windows 2000 and above may be configured to hide file extensions. This can make it difficult to identify the file type. To have Windows show the file extensions:

    • 1. Double-click My Computer.
    • 2. Click View (Win95/98/NT4/Me) or Tools (Windows XP).
    • 3. Click Options (or Folder Options).
    • 4. Click the View tab.
    • 5. Then uncheck “Hide file extensions for known file types” (or “Hide MS-DOS file extensions for file types that are registered”). Click OK to save changes.

The following site has lists of file extensions and the software that can read them:

Once you’ve determined the correct program to use with a particular file type, you will want to set the file association. Windows uses the file associations to select the default program to open a particular file type with.

Changing the settings of the Windows File Associations varies by the version of Windows. For specifics see: WinXP.
