.CAH File Extension
File Type5e Companion App Character File
What is a CAH file?
A CAH file contains information about a Dungeons & Dragons (D&D) character created with 5e Companion App, an Android app for managing characters used in D&D play. It stores information in plain text, which includes attributes and skills for the character.
You will most likely only encounter CAH files if you enjoy playing D&D and use Companion App to manage your characters. The files are meant to only be opened with 5e Companion App.
How do I open a CAH file?
You can open a CAH file with 5e Companion App, which is only for Android devices. Since the CAH file is saved in plain text format, you can also open it with a text editor by changing the .cah file extension to .txt. However, the information will not be displayed the same way as if you opened the file with 5e Companion App.
