What is a HC file?
An .HC file is most commonly an HTTP Custom configuration file used to set up virtual private network (VPN) and SSH tunnels. These files contain connection settings for the HTTP Custom Android app. However, the .HC extension has multiple possible meanings. It can also be a Holy C Source Code File created by Terry A. Davis for the TempleOS operating system, or a secure virtual disk volume created by VeraCrypt.
How to open HC files?
To open an HTTP Custom VPN file, you need the HTTP Custom or HTTP Injector application on an Android device. If the file is a VeraCrypt container, you must mount it using VeraCrypt and provide the correct decryption password. A Holy C file is plain text and opens in any standard text editor like Notepad++ or directly within TempleOS.
Inspecting and converting files
Because .HC files have different purposes, we recommend using viewer.online/hc to identify the actual format of your file. viewer.online/hc can analyze .HC files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
If you have a source code file and need to change it to a standard text format, we recommend file conversion to sensible target formats on convert.guru. You can easily convert text-based .HC files to .TXT or .C formats.
Summary
viewer.online/hc is useful for identifying, inspecting, and understanding .HC files without installing software or dealing with compatibility problems.
