SUMMARY
If you experience unexpected behavior when you work with a Microsoft
PowerPoint file, your presentation may be damaged or corrupted. Symptoms of
a corrupted presentation may include the following:
. Invalid Page Fault, General Protection Fault, or Illegal Instruction
errors.
-or-
. When you attempt to open a presentation, you receive one of the following
error messages:
This is not a PowerPoint Presentation -or-
PowerPoint cannot open the type of file represented by filename.ppt -or-
Part of the file is missing. -or-
. Out of memory errors, or low system resources errors.
If this unexpected behavior is exclusive to one presentation, the
presentation may be corrupted. This article provides some common steps you
can use to attempt the recovery of a damaged presentation. However, keep in
mind that these steps do not guarantee successful recovery of the damaged
file. In some cases, depending on the type of corruption, you will not be
able to recover any data, and you will have to re-create the damaged
presentation.

NOTE: In some cases you may receive these symptoms for reasons other than a
corrupted presentation.
MORE INFORMATION
If you determine that your presentation has been corrupted, try the
following methods to attempt to recover the damaged file. The methods listed
in this article are organized in the following sections:
. General Troubleshooting
. If You Are Unable to Open a Presentation
. If You Are Able to Open a Damaged Presentation

General Troubleshooting
NOTE: Because there are several versions of Microsoft Windows, the following
steps may be different on your computer. If they are, see your product
documentation to complete these steps.

Restart Windows in Safe Mode. To do this, hold down CTRL while you restart
the computer. When you see the Starting Windows message, press F8, and then
select Safe Mode from the Startup menu.

If you are able to open your presentation after Windows has started in Safe
Mode, a system conflict exists that is preventing you from opening your
presentation.

If You Are Unable to Open a Presentation
If you are still unable to open your presentation, use one of the following
methods.
Method 1: Drag the Presentation to the PowerPoint Program File
1. Determine the location of the PowerPoint program on your computer. The
default location for PowerPoint is:
C:Program FilesMicrosoft OfficeOffice10

2. Drag the damaged PowerPoint presentation to the PowerPoint program icon.
Method 2: Double-Click the PowerPoint Presentation in Windows Explorer
To try to open the file, double-click the PowerPoint presentation in Windows
Explorer.
Method 3: Attempt to Insert Slides into a Blank Presentation
To attempt to insert slides into a blank presentation, follow these steps:
1. On the File menu, click New.
2. Click Blank Presentation, and then click OK.
3. If the New Slide dialog box appears, click OK.

The selection you make in this dialog box does not matter. You can delete
this slide after you re-create your presentation.
4. On the Insert menu, click Slides from files, and then click the Find
Presentation tab.
5. Click Browse. Select the damaged presentation and click Open. The Slide
Finder dialog box appears.
6. Click Insert All.

If this operation is successful, all of the slides from the damaged
presentation, excluding the slide master, are inserted in the new
presentation.
7. Save the presentation.

If your presentation does not look the way that you expect after you try
these steps, try to apply the damaged presentation as a template. To do
this, follow these steps:
1. Make a back up copy of your presentation.
2. On the Format menu, click Apply Design.
3. Select the damaged presentation, and then click Apply.
The slide master of the damaged presentation replaces the new slide master.

NOTE: If you begin to experience unexpected behavior, the template may have
corrupted the presentation. In this case, use the backup copy and create the
master slide again.
Method 4: Try to Open the Temporary File Version of the Presentation
When you edit a PowerPoint presentation, it will create a temporary copy of
the file with the name PPT####.tmp, where #### represents a random
four-digit number. This file may reside in the same folder as the
presentation, or it may be in your Temporary file folder. After you rename
the file to have a .ppt extension, you may be able to open this file in
PowerPoint.
1. First check the folder that the presentation was opened from and look for
a file with the name PPT####.tmp.

If you do not find it there, you must search for it. Otherwise skip steps 2
through 4.
2. Click Start, point to Find, and then click Files or Folders.

NOTE: In Microsoft Windows 2000 or Microsoft Windows Millennium Edition
(Me), click Start, point to Search, and then click For Files or Folders. In
Microsoft Windows XP, click Start and then click Search.
3. In the Named box or the Search for files or folders named box, type
PPT*.tmp.
4. In the Look in box, click My Computer, and then click Find Now or Search
Now.
5. If you do find the file, follow these steps:
1. Right-click the file, and then click Rename on the shortcut menu.
2. Change the the old file name extension from .tmp to .ppt, so that the
file name resembles the following: PPT####.ppt
3. Try to open the file in PowerPoint.
If more than one file corresponds to the last time that you saved your
presentation, you may have to open each file to see if any one is the
temporary copy of the presentation.
Method 5: Try to Open the Presentation in PowerPoint Viewer
If you are able to open the presentation in the PowerPoint Viewer, your
PowerPoint installation may be corrupted or the presentation may contain
corrupted objects.

For additional information, click the article number below to view the
article in the Microsoft Knowledge Base:
126492 PPT: PowerPoint Viewer (32-Bit) Available from Online Services

Method 6: Move the File to Another Computer
In some cases, if you copy the PowerPoint file to a different computer, you
can open the presentation. If you are able to open the file, look at each
slide to determine if there are any blank object placeholders. If there are,
delete them. Resave the presentation and then copy the presentation back to
the original computer.
Method 7: Move the File to Another Disk
Windows may not be able to read the file from where it is currently saved.
Copy the file to another disk. For example, copy the file from a floppy disk
to the hard disk.

NOTE: If you are unable to copy the file from the disk on which it is saved,
it may be cross-linked with other files or folders, or it may be located in
a damaged sector of the disk. Try Method 8.
Method 8: Run ScanDisk
Run ScanDisk to repair all errors on the drive. Have it repair all
cross-linked files and convert lost fragments to files.

NOTE: Even though ScanDisk may determine that your file is cross-linked and
repair it, this is not a guarantee that PowerPoint will be able to read the
file.

If You Are Able to Open a Damaged Presentation
Method 1: Attempt to Apply the Damaged Presentation as a Template
Insert the slides into a blank presentation, and then apply the damaged
presentation as a template to preserve the master. To do this, follow these
steps:
1. On the File menu, click New.
2. Click Blank Presentation, and then click OK.
3. If the New Slide dialog box appears, click OK.

The selection you make in this dialog box does not matter. You can delete
this slide after you re-create your presentation.
4. On the Insert menu, click Slides from files, and then click the Find
Presentation tab.
5. Click Browse, select the damaged presentation, and then click Open. The
Slide Finder dialog box appears.
6. Click Insert All.

If this is successful, this operation inserts all of the slides from the
damaged presentation, excluding the slide master, in the new presentation.
7. Save the presentation. If your presentation does not look the way you
expect, try to apply the damaged presentation as a template. To do this,
follow these steps:
1. Make a backup copy of your presentation.
2. On the Format menu, click Apply Design.
3. Select the damaged presentation, and then click Apply.
The slide master of the damaged presentation replaces the new slide master.

NOTE: If you begin to experience unexpected behavior, the template may have
corrupted the presentation. In this case, use the backup copy and re-create
the master slide.
Method 2: Paste the Slides from the Damaged File into a New File
Use a copy and paste operation to move the slides from the damaged
presentation to a blank presentation. To do this, follow these steps:
1. Open the damaged presentation.
2. On the File menu, click New.
3. If the New Slide dialog box appears, click OK.
4. On the View menu, click Slide Sorter. If you receive error messages when
you switch views, try changing to Outline view instead.
5. Click a slide to copy.
6. On the Edit menu, click Copy. If you want to copy more than one slide at
a time, hold down SHIFT and click each slide that you want to copy.
7. Switch to the new presentation. On the Window menu, click the new
presentation option.
8. On the View menu, click Slide Sorter.
9. On the Edit menu, click Paste.
10. Repeat steps 5 through 9 until the entire presentation is transferred.
NOTE: In some situations, one damaged slide may cause a problem for the
entire presentation. If you notice strange behavior within the new
presentation after you copy a slide to it, that slide is most likely
corrupted. Either re-create the slide or copy portions of the slide to a new
slide.
Method 3: Save the Presentation as RTF (Rich Text Format)
If there is corruption throughout the presentation, the only option to
recover the file may be to save as RTF. This method, if successful, recovers
only the text that appears in Outline view. To do this, follow these steps:
1. Open the presentation.
2. On the File menu, click Save As.
3. In the Save File As Type list, click Outline/RTF(*.rtf).
4. In the File Name box, type the name that you want, pick a location to
store the file, and then click Save.
5. Close the file.
NOTE: To continue working after you open the RTF file, click Open on the
File menu, and in the Files of type list, click All Outlines or All Files.
RTF files do not appear if you select the Presentations option.
