SYMPTOMS
When you attempt to open a file you receive the following error message:

Sorry, the file cannot be opened because part of the file is missing.

This error message typically occurs with files that are saved on removable media, but may also occur with damaged files on a local hard disk.



CAUSE
This error message may occur when any of the following conditions is true:
 * The disk was improperly handled while you were working with the presentation. For example, while the presentation was open, you removed a floppy disk or Zip disk from the drive, or you exchanged the disk with another disk.
 * A network interruption such as a lost connection occurred while you were saving, closing, or working on a file that you opened from a network drive.
 * A power outage, spike, or brownout occurred while PowerPoint was attempting to use the disk.
 * A virus scanner or other disk utility locked the disk while the file was open in PowerPoint.
 * Your disk or disk drive is damaged or is not functioning properly.
 * The presentation was too large to fit on the disk, and so PowerPoint was only able to save part of the presentation.



WORKAROUND
In most cases, this error message indicates that the file is damaged, and it is unlikely that you can recover the file. However, in some cases you may be able to recover the file by using one of the following methods.

Method 1: Open the File on a Different Computer
Transfer the file to another computer that is running the same version of PowerPoint. Or, if you have a Windows-based computer on which PowerPoint is installed, attempt to open the file on that computer.

Method 2: Use a Different Method to Open the File
Open the file by using one of the following methods:
 * Double-click the file in the Finder.
 * Start PowerPoint. Drag the file from Windows Explorer to PowerPoint.
 * In PowerPoint, click Slides from File on the Insert menu.

Method 3: Install the Microsoft Office 2001 Service Release 1 (SR-1) Patch
Installing the Microsoft Office 2001 SR-1 patch may allow you to open the presentation. It may also prevent the problem from occurring again.

You can obtain the Microsoft Office 2001 Service Release 1 file from the following Microsoft Web site:

http://www.microsoft.com/mac/downloads.aspx?pid=download&location=/mac/download/office2001/update_905.xml&secid=10&ssid=25&flgnosysreq=True

Method 4: Diable Fast Saves
Another method that may work is to turn off the Allow fast saves option in PowerPoint 2001, and then perform a full save of the document. To do this, follow these steps:
 * 1) Start PowerPoint 2001.
 * 2) Open a document, and then click Preferences on the Edit menu.
 * 3) In the Preferences dialog box, click the Save tab, and then click to clear the Allow fast saves check box.
 * 4) Open the presentation that exhibits the behavior described in the &quot;Symptoms&quot; section of this article.
 * 5) Make at least one change to the presentation, such as adding a space or other symbol, or make a formatting change.
 * 6) Save the presentation.

NOTE With the Allow fast saves option turned off, the next time that you save the presentation, the presentation completes a full save.

Method 5: Manually Move the File to a Network Share
NOTE: Use this method if the file was saved on a network share when you received the error message.

Save the presentation to a local drive, and then use the Finder to transfer the file to the network share in question. Mac OS saves files differently to a network server than an application does.



MORE INFORMATION
Keep the following tips in mind when you work with files that are stored on removable media:
 * Do not remove the disk from the drive while the file is open in PowerPoint.
 * Make sure that the disk has enough free space to store your presentation.
 * If the computer's power supply is unreliable, repair or replace the power supply, or purchase an uninterruptible power supply (UPS).
 * Copy the file to your hard disk, make the changes that you want, save the file, and then copy the file back to the removable media or network drive.
