#### 17.8.7 Specifying jumps to external files

DITA2Go produces links to external sources from HyperLink and HyperFile PI markers:

When a HyperFile link specifies an absolute path (which must start with a drive letter), DITA2Go removes any “file:///” URL prefix to the path, which is not needed in RTF. For example:

    HyperFile="file:///g:/omnisys/ug/out/dita2go.pdf"

becomes:

    !EF('g:/omnisys/ug/out/dita2go.pdf')

HyperLink and HyperFile are implemented in WinHelp with the !EF macro; see §17.9.1 Using a hypertext marker to invoke a macro.
