What is an EXTR file?

An EXTR file is an encrypted folder used by the COW operating system, which is an operating system based on Linux for select mobile devices. It contains a program and a Main.py script that stores instructions for where the COW system installer should install the program. EXTR files are downloaded to a mobile device from the COW App Store and then decrypted and opened automatically by the COW system when installing the downloaded program.
