File handling is the process of creating, reading, writing, updating, and deleting files on a computer system. It involves managing files stored on a storage device, such as a hard drive or a USB drive, by performing various operations on them. File handling is an essential aspect of programming and is used in various applications to store and retrieve data efficiently.

File Handling
File handling in programming refers to the operations and techniques used to manipulate files on a computer system. It involves reading, writing, creating, updating, and deleting files stored on a storage device, such as a hard drive or network server.
Key Concepts in File Handling:
- File: A collection of data stored on a storage device that can be accessed by programs.
- File Pointer: An indicator that specifies the current position within a file for reading or writing.
- File Modes: Different access modes for files, such as "read-only," "write-only," or "read-write."
- File Formats: The way in which data is structured and encoded in a file.
Types of File Handling Operations:
- Opening: Establishing a connection between a program and a file before performing any operations.
- Reading: Retrieving data from a file and transferring it to the program's memory.
- Writing: Storing data in a file from the program's memory.
- Closing: Ending the connection between the program and the file to release resources.
- Seeking: Moving the file pointer to a specific location within the file.
- Truncating: Reducing the size of a file by removing data from the end.
Benefits of File Handling:
- Data Storage: Files provide a persistent way to store data for later retrieval or processing.
- Data Sharing: Files can be shared among different programs or computers for collaboration and access to data.
- Data Persistence: Data stored in files can survive program crashes or system reboots, ensuring its availability in the future.
- Input and Output: Files can serve as input sources for programs (e.g., reading configuration files) or output destinations (e.g., writing log files).
- Data Backup and Recovery: Files allow for the backup of data in case of system failures or accidental deletion.
