.HC File Extension

An HC file is a container file created by VeraCrypt, disk encryption software. It contains a virtual encrypted disk. HC files can be configured to a specific KB, MB, or GB volume size and are password protected.

To create an HC file select Tools → Volume Creation Wizard and click Next. Select the container type, name the file, and choose the location where you would like to save the file.

You can open an HC file simply by double-clicking the file and it will open in VeraCrypt.

VeraCrypt is a successor to TrueCrypt, an encryption tool for desktop operating systems. TrueCrypt was abandoned by its developers because of security holes that were fixed by another group of developers then repackaged as VeraCrypt. VeraCrypt is free and open source.

An HC file is a Holy C source code file, which is used with the TempleOS operating system. It contains code that is meant to be compiled within TempleOS. HC files can be opened and edited in any text editor, but can be compiled and run only in TempleOS.

In the early 2000s, programmer Terry A. Davis began creating an operating system that came to be known as TempleOS. Davis, who was a schizophrenic, claimed that God commanded him to create TempleOS. While the operating system is most useful for creating simple video games, it includes a number of biblical references, including a game named After Egypt. Davis claimed that a number of the OS's specifications were set down by God, and after publishing TempleOS in 2013, Davis announced that "God's temple is finished."

As part of developing TempleOS, Davis also developed the Holy C programming language. Holy C is a variant of the C programming language that is used only by TempleOS. Those who create TempleOS programs write those programs in Holy C, and they save and distribute their work in HC files.

While you can open and edit a Holy C source code file in any text editor, HC files are meant to be edited, compiled, and run within the TempleOS operating system. TempleOS includes its own source code editor that allows developers to open, edit, and create HC files.
