What is a .prc file?

A .prc file can be used to store 3D models, but it is more commonly used to store eBooks. The full form of PRC is Product Representation Compact, and it is a file format that was developed by Adobe Systems for storing 3D data. PRC files can be embedded in PDF files, and they can be used to share 3D models with other users.

However, the .prc file extension is also used for Mobipocket eBook files. Mobipocket was a French company that developed the Mobipocket Reader software, and they used the .prc file extension for their eBook format. PRC files can contain text, images, tables, and JavaScript, and they can also be DRM-protected.

So, while it is true that a .prc file can be used to store 3D models, it is more commonly used to store eBooks. The specific use of a .prc file will depend on the software that was used to create it.

If you are looking for an ebook format that is supported by a wide range of devices and publishers, then EPUB is the better choice.

To create a .PRC file from scratch, you will need to use a software application that can create and compile resource files. There are a few different applications that you can use, such as:

Constructor, PilRC, Mobipocket Creator

Once you have chosen an application, you will need to create a new resource file and add the following resources to it:

  • A header resource that contains the file's name, version number, and creator ID.
  • A code resource that contains the application's code.
  • A data resource that contains the application's data.

Once you have added all of the resources to the file, you can compile it into a .PRC file. The specific steps for compiling the file will vary depending on the application that you are using.
