Troubleshooting Problems Opening DTD Files

Frequent DTD Opening Issues

Microsoft Notepad Removed

When trying to open your DTD file, you get the error "Can't Open DTD File Type". If this is the case, it's usually due to the fact that you do not have Microsoft Notepad for - installed on your computer. The typical path of opening your DTD with a double-click won't work because - cannot make the program connection.

Tip: When another DTD application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Outdated Microsoft Notepad

It is possible that your version of Microsoft Notepad isn't able to open your Document Type Definition File file due to incompatibility. You will need to download a newer version of Microsoft Notepad if you don't have the right version. Your Document Type Definition File file was probably created by a newer release of Microsoft Notepad than what's currently installed your computer.

Tip: If you right-click on your DTD file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Regardless, most of the DTD file opening problems relate to not having the right version of Microsoft Notepad installed.

Other DTD File Opening Causes

In the majority of cases, installing the right version of Microsoft Notepad will resolve your issue. If you are still having problems opening DTD files, there may be other issues that are preventing you from opening these files. Issues that aren't software-related:

• File references in the Windows Registry for DTD are wrong
• Deletion of the DTD file description from the Registry by mistake
• Corrupt install of Microsoft Notepad or other DTD-related program
• Your DTD file is corrupted (issues with your Document Type Definition File file itself)
• DTD file integrity has been compromised by malware
• DTD-related hardware has device drivers that obsolete
• Insufficient system resources to successfully open Document Type Definition File files
