Office 2007 Documents .docx, .xlsx and .pptx Are Opened As ZIP Files (Doc ID 741692.1)

Last updated on NOVEMBER 29, 2016

Applies to:

Portal - Version 9.0.4 to 10.1.4.2 [Release 10g to 10gR2]
Information in this document applies to any platform.
Checked for relevance on 24-Oct-2014

Symptoms

When downloading certain files with Internet Explorer the file is treated as a zip type archive and opened with the registered zip utility rather than opened with the expected application for the file type.

This only happens with Internet Explorer and files of type “.docx”, “.xlsx” and “.pptx”.  When using Firefox or other browsers the file is opened with the application registered for the file extension.

If the file is saved to the operating system and then opened locally the expected Office 2007 application is used to open the file.
The issue only occurs when using Internet Explorer to directly open the file through the Item Access link in Portal.

Steps To Reproduce:

  1. Upload a file created with Office of type .docx, .xlsx or .pptx.
  2. Attempt to open the item by selecting the item link in Portal using Internet Explorer.
  3. Files of the type are passed to the registered zip utility.
    Other files are passed as expected to their registered utilities.

 

Changes

This problem begins when starting to use Microsoft Office 2007 file types  “.docx”, “.xlsx” and “.pptx”.
