What is a CCC file?
Cache file used by Dev-C++, , an open-source Integrated Development Environment (IDE) for C/C++ software programming; contains data utilized by the program to complete C++ code, which enables quicker development.
The cache file is created when you accept the autocompletion function when Dev-C++ is first run. After accepting the function, the program will parse some files and create the CCC cache. The file is located in the \%APPDATA%\Dev-Cpp\ directory.
