1.	Quit Visio .
2.	Start Windows Explorer, and then locate the drawing file that you want to open.
3.	Double-click the drawing file.

Method 3: Open the temporary copy of the drawing file

When you modify a Visio drawing, a temporary copy of the drawing file is created. The temporary copy of the drawing file is named ~$$FileName.~vsd. The temporary copy of the drawing file is typically created and stored in the same folder as where your drawing is located.

To open the temporary copy of the drawing file, do the following:

1.	Start Visio, and then open your drawing.
2.	Start Windows Explorer, and then locate the folder where your drawing is stored. Look in this folder for the temporary copy of the drawing file. The temporary copy of the drawing file is named ~$$FileName.~vsd. Note If the temporary copy of the drawing file is not located in the folder where your drawing is stored, search the hard disk for the temporary copy of the drawing file. To search the hard disk for the temporary copy of the drawing file, do the following: Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps. a. Click Start, and then click Search. b. Click All files and folders. c. In the All or part of the file name box, type ~$$FileName.~vsd, and then click Search.
3.	Change the extension of the temporary copy of the drawing file to .vsd. To do this: a. Right-click the temporary copy of the drawing file, and then click Rename. b. Change the extension of the temporary copy of the drawing file from ~.vsd to .vsd.
4.	Try to open the temporary copy of the drawing file that you renamed.

Method 4: Use the Microsoft Office Visio Viewer to open the drawing

Install Microsoft Office Visio Viewer 2003 or Microsoft Visio Viewer 2002, and then use Visio Viewer to open and view your drawing. When you install Visio Viewer 2003, you can use Microsoft Internet Explorer 5.0 or a later version of Internet Explorer to view Visio drawings and diagrams that are created with Visio 2007, Visio 2003, Visio 2002, Microsoft Visio 2000, or Microsoft Visio 5. For more information about Visio Viewer 2007, visit the following Microsoft Web site:When you install Visio Viewer 2003, you can use Microsoft Internet Explorer 5.0 or a later version of Internet Explorer to view Visio drawings and diagrams that are created with Visio 2003, Visio 2002, Microsoft Visio 2000, or Microsoft Visio 5. For more information about Visio Viewer 2003, visit the following Microsoft Web site: When you install Visio Viewer 2002, you can use Internet Explorer 5.0 or a later version of Internet Explorer to view Visio drawings and diagrams that are created with Visio 2002, Visio 2000, or Visio 5. For more information about the Visio 2002 Viewer, visit the following Microsoft Web site: If you can open your drawing in the Visio Viewer, the installation of Visio on your computer may be damaged or your drawing may contain one or more objects that may be damaged.

Method 5: Copy the drawing file to another computer

Copy the drawing file to another computer that has Visio installed on it. If you can open your drawing on that computer, save the drawing file to a different folder on the hard disk of that computer, and then copy the drawing file back to the original computer.

Method 6: Copy the drawing file to another disk on your computer

Windows may not be able to read the drawing file from where the drawing file is currently saved. Copy the drawing file to another disk on your computer. For example, copy the file from a floppy disk to the hard disk. After you copy the drawing file to a different disk on your computer, try to open the drawing file.

Note If you cannot copy the drawing file from the disk where the drawing file is saved, the drawing file may be cross-linked with other files or folders, or the drawing file may be located in a damaged sector of the disk. To troubleshoot this issue, follow the steps in Method 7.

Method 7: Detect and repair errors on the hard disk

If you are running Microsoft Windows Server 2003, Microsoft Windows XP, Microsoft Windows 2000, or Microsoft Windows NT 4.0, use the Check Disk tool to detect file system errors or bad sectors on your hard disk.

For more information, click the following article numbers to view the articles in the Microsoft Knowledge Base:

Methods to try to help prevent damage to drawings

You cannot prevent all corruption that may occur to files. Hard disks may wear out, power supplies may fail, and other unforeseeable events may occur that cause files to become damaged. The following tips and suggestions may help reduce the number of damaged files that occur in Visio and in other programs.

Optimize the AutoRecover setting in Visio

Configure the AutoRecover setting to a value that works for you. If your computer stops responding or if you lose power unexpectedly, Visio opens the AutoRecovery file the next time that you start the program. The AutoRecovery file may contain unsaved information that would otherwise be lost from your original drawing file. If your original drawing file was damaged, you may be able to recover information from the AutoRecovery file.

To configure the AutoRecover setting in Visio:

1.	Start Visio.
2.	On the Tools menu, click Options.
3.	Click the Save tab or the Save/Open tab.
4.	Select the Save AutoRecover info every check box, and then specify the time in minutes that you want. By default, the AutoRecover setting is set for 10 minutes.
5.	Click OK.

Make sure that the power supply is consistent

A power supply that is not consistent can cause damage to files, even if you do not lose power. A power supply that spikes or that is not sufficient can affect the read process and write processes on your computer, and may cause damage. If the power supply in your area is inconsistent, use a surge protector. Surge protectors can help prevent damage on your computer if power spikes occur. You may also consider using an uninterruptible power supply (UPS). UPS units supply your computer with power even if there is a power outage. Contact your hardware vendor for more information about how to obtain either of these devices.

Back up your data

Make sure that you back up your data regularly. For example, store a backup copy of your drawing on a different volume on the hard disk. Or, depending on your requirements and on your environment, implement other backups or other fault-tolerant solutions on your computer. Some fault-tolerant solutions, such as Redundant Array of Independent Disks (RAID), are typically only practical for larger networks. Other backup options include the following:

•	Tape backup
•	CD backup
•	Mirrored volume
•	RAID-5 volume

Work with your data locally

If you work in a network environment and you experience corruption frequently, you may want to consider copying your files to your local computer before you open the file or before you modify the file. Copy the file to your desktop by using My Computer or by using Windows Explorer. When you work with files that are stored on your local computer, you prevent read issues or write issues that may be caused by network connectivity issues such as the following:

•	Slow network connections
•	Dropped network connections
•	Spikes in network traffic

You may also want to consider working from the hard disk and not working from removable media such as a floppy disk or a ZIP drive. The more media and the more device drivers that are involved in a save operation, the more the increased chance of file damage.
