The hmxp file suffix is associated with Help & Manual, a documentation authoring and content management program from EC Software for Microsoft Windows.
An hmxp file contains a Help & Manual project in uncompressed XML form. The project can include the structured source content and settings used to produce documentation.
Help & Manual also supports a compressed project form, while HMXP is used when the project is kept uncompressed.
Open an hmxp file in Help & Manual on Microsoft Windows. In the program, use its open-project command and select the file.
Help & Manual can publish or export an HMXP project to supported documentation output formats. Open the project in Help & Manual and use its publishing or export tools.
There is generally no need to convert an HMXP file simply to continue editing the project; it is already the uncompressed project format used by the program.
