The extended attributes did not fit in the buffer.
Updated: Feb 21, 2026
Technical Meaning
This error code indicates that the extended attributes associated with a file or directory did not fit within the buffer allocated for their storage. Extended attributes are additional metadata that can be attached to files and directories in certain file systems, such as NTFS.
Error Details
The ERROR_EAS_DIDNT_FIT error is returned when an attempt to retrieve extended attributes results in a buffer that is too small to contain all the data. This typically occurs during operations involving file or directory enumeration or attribute retrieval where the system expects more data than can be accommodated by the provided buffer.
Usage Context
This error code is relevant in scenarios where applications need to query or manipulate extended attributes of files and directories. It may appear when using functions such as GetFileInformationByHandleEx with the FileExtendedAttributesInfo information class, or during operations involving directory enumeration that require attribute data.
Developer Interpretation
When encountering this error, developers should ensure that buffer sizes are sufficient to accommodate all extended attributes. This may involve dynamically allocating larger buffers based on known or estimated attribute sizes, or adjusting the operation context to use a more appropriate buffer size.
