What is an HDC file?

HDC files mostly belong to Hero Lab. The HDC file extension appears in several contexts. Its most common role is as a file for game characters. In this use case, the file stores character data for role‐playing or strategy games. Some versions use XML encoding while others use UTF-16 (BE) to structure the data. This format is used by tools such as Hero Designer and Hero Lab to manage and save character details.
Aside from game data, HDC files serve other roles. Some are used as firmware update files. For example, Panasonic uses an HDC file type for firmware updates on devices like the HDC-SD1000 Camcorder. These files are sometimes called Panasonic HD Writer files. More information is available on the Panasonic website.
In another instance, HDC files act as dictionary files. These files store data for handheld dictionaries and are integrated with tools like GoldenDict and Babylon Glossary Builder. For more details on this usage, you can visit the GoldenDict website.
To sum up, use the proper software for the specific context:

Game Character Files: Open with Hero Designer or Hero Lab.

Firmware Files: Use Panasonic's device update utilities.

Dictionary Files: Open with GoldenDict or compatible applications.

FilExt.com note: Always keep a backup before making any changes and consider checking the file’s contents with a text editor if the encoding appears to be text based.
