#### 18.3.3 Organizing source files for HTML Help

Compiled HTML Help has the following limitation on file placement: a CHM can contain files located only in the same directory as the .hhp file (HTML Help project file) or in a subdirectory. Sibling directories, parent directories, and absolute paths elsewhere do not work. CHM content is organized in an internal file system that duplicates the external file structure, but with the directory containing the .hhp file as the root. Therefore, references to directories outside this structure do not work.

If your project includes DITA files on different paths that reference each other, you might have to reorganize them to conform to this HTML Help limitation. If your project includes referenced graphics files, DITA2Go can copy the graphics files to the project directory (or a subdirectory) before beginning the conversion. See §18.3.9 Locating graphics files for HTML Help.
