Question details
Users are unable to open older .vsd format files using Microsoft Visio 2019 or Visio Plan 2.

- Product
- Microsoft Visio 2019
- Device & OS
- not provided
- Scenario
- Attempting to access, edit, or convert legacy VSD flowchart or diagram files in newer versions of Visio.
- Observed behavior
- The older Visio file fails to open, which may be caused by specific file corruption, outdated application software, or restrictive Trust Center file-blocking settings.
Verify that your Microsoft Office suite is fully activated and ensure you have a backup copy of the original .vsd file before modifying security settings.
Modify Trust Center Settings to Allow VSD Files
Visio's security settings may block older file formats by default. Adjusting the Trust Center options can resolve this restriction and allow the file to open.
Microsoft introduced stricter security measures in modern Office applications. Older VSD files are sometimes blocked by default to protect your computer from potential macro or file-based vulnerabilities.
Launch Microsoft Visio 2019. Click on the 'File' tab in the top-left corner, and then select 'Options' located at the bottom of the left-hand navigation pane.
In the Visio Options window, select 'Trust Center' from the left menu, then click on the 'Trust Center Settings...' button.
Navigate to 'File Block Settings' within the Trust Center. Look for the older Visio 2003-2010 file types (.vsd) in the list and ensure that the boxes preventing them from opening are unchecked.
Click 'OK' to save your changes and exit the settings menu. Try opening your older VSD file again to see if the issue is resolved.

Update Visio Software and Test for File Corruption
Identify whether the issue is caused by an outdated version of Visio or if the specific VSD file is corrupted by testing an alternative file.

Frequently Asked Questions
Does Visio 2019 still support older VSD formats natively?
Yes, Visio 2019 and Visio Plan 2 still retain support for older VSD files. The older VSD format was replaced by VSDX, but the ability to read and convert legacy files was kept intact.
How can I convert my old VSD file to the new VSDX format?
Once you successfully open the older VSD file in Visio 2019, navigate to 'File' > 'Save As', choose your save destination, and select 'Visio Document (*.vsdx)' from the Save as type dropdown menu.
What should I do if my VSD file is actually damaged?
If testing reveals the file is damaged, try opening it in a previous version of Visio if you have access to one, or restore an earlier version of the file from your local backups or cloud storage history.
