file handling

File handling is the process of creating, opening, reading, writing, and closing files on a computer. It allows programs to store information, such as documents or data, in files so they can be accessed later. Think of it like opening a notebook to read or write notes; the computer does this electronically with files. Proper file handling ensures data is saved correctly and remains accessible without corruption. It's an essential part of managing data efficiently and securely in software applications.
