OpenOffice.org generated HDL files as part of its programming and development workflow. The files contain C header declarations rather than user documents or office-suite content.
An HDL file belongs to the generated source files for OpenOffice.org and is used with the other source and build files required to compile or extend the software. OpenOffice.org was available for multiple platforms.
Because an HDL file contains generated C header declarations, it can be opened as text in a source-code editor or other plain-text editor. For development work, keep the file with the OpenOffice.org source tree and use the project's build tools rather than treating it as an end-user document.
If the file was generated by a build process, editing it directly may cause the changes to be overwritten.
HDL files are source files and do not normally have a useful document conversion target. If different declarations are needed, regenerate the file from the corresponding OpenOffice.org source or build process. It can be saved as another plain-text file, but that does not convert it into a different programming format.
