I uploaded a file on my Mac, but the attached file does not open.

This issue may occur if the document has been saved and then uploaded without the proper file extension. This is related to the way Mac operating systems handle files and file extensions. Extensions are the 3-4 characters that follow the "dot" at the end of a file name. The operating system uses extensions to identify compatible software that can open and read the file. For example, a file ending ".doc" is identified as a MS Word document, while ".ppt" identifies a PowerPoint presentation.

To remedy this situation:

• Remove the file from your work.
• Re-save your work, making certain to include the extension in the document path.
