ECP is a project file created by easyC development environment. ECP files are typically used for scientific and educational purposes. ECP file stores program source code created by using ‘drag and drop’ method of visual code creation process.

ECP documents store data in plain text format and are used by easC during code compilation process. ECP files compiled into executable code can be uploaded in Vex robots for execution. Latest iteration of easyC, designated v5, doesn’t support ECP files any more; last iteration that used this format was easyC v2.
