The object identifier does not represent a valid object.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_OBJECT_NOT_FOUND error code indicates that the specified object identifier does not correspond to a valid object within the system. This can occur in various contexts, such as file operations, directory enumeration, or other object-based APIs.
Error Details
This error is returned when an operation fails because the provided object identifier (such as a path, handle, or unique identifier) cannot be resolved to a valid object. The exact nature of the object can vary depending on the API and context in which it is used.
Usage Context
The ERROR_OBJECT_NOT_FOUND error code can appear in different scenarios where an object-based operation fails due to an invalid identifier. Common contexts include file system operations, process management, and other APIs that rely on object identifiers.
Developer Interpretation
When encountering this error, developers should verify the following:
- The correctness of the object identifier (e.g., path, handle) provided in the API call.
- Whether the object exists within the expected context or scope.
- Any potential race conditions where the object might have been deleted or modified between the time it was identified and when the operation was attempted.
