EPUBCheck PKG-014 is a warning message: “The EPUB contains empty directory "…".” The EPUB archive contains an empty folder, which serves no purpose and is reported so you can remove it.

- Official message (EPUBCheck 5.4.0): The EPUB contains empty directory "%1$s".
- Default severity: Warning

## Typical causes

- A folder left behind after moving or deleting files while editing the book.

## How to fix it

- Delete the empty folder from the book's source and rebuild the archive.
- Rebuild the archive with the mimetype file first and stored uncompressed, for example from the folder that contains the book: zip -X0 book.epub mimetype and then zip -rX9 book.epub META-INF OEBPS (use your own folder names).
