Lesson Content/Board Summary
CATEGORIES OF FILES
1. Categories of Files
Files are classified based on the level of secrecy or importance of the information they contain. This classification determines who can access them.
- Open File: Contains information that can be accessed by any authorized staff member. It usually deals with routine matters.
- Confidential File: Contains information that is not for general circulation and is restricted to specific individuals or departments. Access requires authorization.
- Secret File: Contains highly sensitive information that, if disclosed, could cause serious damage to an organization or individual. Access is strictly limited to a very small number of designated persons.
- Top Secret File: Contains information of the highest sensitivity, the unauthorized disclosure of which would cause exceptionally grave damage. Access is granted only on a strict “need-to-know” basis to the highest-ranking officials.
2. Movement of Files
File movement refers to the process of transferring a file from one department or individual to another within an organization. This movement must be properly recorded to ensure accountability and easy retrieval.
Importance of File Movement Register
A file movement register is a record book or system used to track the location of files within an organization. Its importance includes:
- Tracking: Helps to locate any file quickly, preventing loss or misplacement.
- Accountability: Shows who has a file at any given time, making individuals responsible for its custody.
- Security: Ensures sensitive files are not mishandled or accessed by unauthorized persons.
- Efficiency: Reduces time spent searching for files, improving office productivity.
- Audit Trail: Provides a historical record of a file’s movement for audit purposes.
3. Types of File Folders and Jackets
File folders and jackets are used to hold and organize documents within filing cabinets or systems.
- Manila Folders: Basic, commonly used folders made of heavy paper, suitable for general documents.
- Suspension/Hanging Folders: Designed with hooks to hang on rails inside filing cabinets, often used with manila folders inside.
- Pocket Folders: Folders with built-in pockets to hold loose documents, often used for presentations or reports.
- Expanding Files/Wallets: Folders with gusseted sides that expand to hold a large volume of documents.
- File Jackets: Similar to folders but often fully enclosed on three sides, providing more protection for documents.
- Pressboard Folders: Made from durable, stiff material, suitable for frequently accessed or heavy files.

For pupils who need more support, the teacher will provide more one-on-one guidance during the handling of file samples and review the definitions individually.
Note for teachers using this lesson plan
Ensure that actual or mock samples of files, folders, and a file movement register are available for demonstration. Emphasize the practical application of file management in real-world office settings. Encourage pupils to ask questions regarding the security implications of different file categories.
