Notes about the HPD file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The HPD file type is primarily associated with 'HotDocs' by Matthew Bender & Company, a member of the LexisNexis Group. HotDocs is a program often used by the legal profession to trasfer documents. It is a variation of PDF. The PDF file created by HotDocs is from a .HPT file. Note that both .HPD and .HFD files do not save the answers like answer files do, but save the form as it appears. Because of this, if you add any further information to these documents, any calculations in the form templates will no longer be carried out.
