What is an HFD file?
An .HFD file is a data format that usually functions as a HotDocs Form Document created by HotDocs. It contains document templates and digital forms used by legal professionals and businesses for automated document assembly. Another common use for the .HFD extension is an Apple HealthKit database file, which is generated by the Apple Health app on iOS devices to store fitness and medical data.
How to open HFD files?
To open a HotDocs Form Document, you typically need HotDocs Developer or the free HotDocs Player. If your .HFD file is a health database, it is natively read by the Apple Health application or can be accessed using SQLite database viewers. Because these files serve completely different purposes, identifying the exact format is an important first step.
Inspect and analyze HFD files online
If you do not know the origin of your file, viewer.online/hfd can analyze .HFD files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available. This helps you determine if you are looking at a legal template or a mobile health database.
Summary
viewer.online/hfd is useful for identifying, inspecting, and understanding .HFD files without installing software or dealing with compatibility problems. It provides a secure way to explore the file contents and decide which desktop application you need to use next.
