YML File Complications

Troubles Opening YML Files

Microsoft Notepad Not Present

You encounter an error message such as "%%os%% Can't Open YML Files" when trying to open your YML. Usually, this is because you do not have Microsoft Notepad for %%os%% installed. The OS won't know what to do with your YML file, so double-clicking to load the file doesn't work.

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

Obsolete Version of Microsoft Notepad

Occasionally, you might have an outdated version of Microsoft Notepad installed that's incompatible with your YAML Document type. Installing the latest version of Microsoft Notepad from Microsoft Corporation is recommended. Your YAML Document file was probably created by a newer release of Microsoft Notepad than what's currently installed your computer.

Tip: You can sometimes get hints about the right program version by right-clicking on the YML file, selecting "Properties", and looking at the version information.

Ultimately, most of the difficulties opening YML files are due to having the wrong version of Microsoft Notepad installed.

Other Causes of YML File Opening Problems

You can still experience errors opening YML files even with the latest version of Microsoft Notepad installed on your PC. If you are continuing to have errors with loading YML files, other external issues might be to blame. These issues include:

• YML file type Registry entries are wrong
• Accidental deletion of the description of the YML file in the Windows registry
• Invalid installation of a YML-associated program (eg. Microsoft Notepad)
• The YML itself is corrupted
• YML file integrity has been compromised by malware
• Hardware related to YMLs has device driver corruption
• Insufficient system resources to successfully open YAML Document files
