fileAccessControl.cnf is a configuration file using which you will provide read/write/delete access for a particular folder to manage files inside it.
pub.file:listFiles, pub.file:copyFile, pub.file:deleteFile, pub.file:checkFileExistance services can not be executed unless fileAccessControl.cnf file is appended with file paths.
