ERROR_SHORT_NAMES_NOT_ENABLED_ON_VOLUME
8.3 short-name generation is disabled
ERROR_SHORT_NAMES_NOT_ENABLED_ON_VOLUME is a Win32 result associated with legacy path compatibility and short-name queries.
What the result means
The requested operation depends on 8.3 short names, but they are disabled on the volume.
What to check
- Use long paths and Unicode-capable APIs whenever possible.
- Check whether the file predates the policy and already has a short name.
- Identify the legacy component that still requires 8.3 aliases.
- Avoid enabling short names globally as a first response.
Recommended handling
Modernize the caller or enable the feature only for a justified compatibility requirement. Changing the setting does not retroactively create short names for every existing file.
