Symptoms

When you try to open or save a file you downloaded from the Internet, you may experience one of the following symptoms:

  • When you try to open the file, you are prompted to choose a program to view the file, and this may occur even if you have a program associated with this file type.
  • When you try to save this file, the file may be saved with a document (.doc) file extension, and this may occur even if the file is not a document.

Cause

This issue can occur if both of the following conditions exist:

  • The Web address of the file you downloaded does not have a file extension.
  • The file you downloaded does not contain a content-disposition header.

Resolution

To resolve this issue, contact the administrator of the Web site to request a file extension be added to the file, or a content-disposition header be added to the file.

To work around this issue if you know the proper file extension, rename the file, and add the appropriate file extension. To rename a file, right-click it, type the new file name, and then press ENTER.
