Files, Folders and Storage

Good file management saves time and prevents loss.

Files and Folders

A file is a saved unit of data. A folder groups related files. Use a clear hierarchy: School → JSS2 → Computer Studies → Assignments.

Names and Extensions

File extensions tell the computer the file type: .docx (document), .xlsx (spreadsheet), .jpg (image), .mp4 (video), .pdf (portable document). Name files so you can find them later: 2026-05-12-computer-assignment.docx.

Backups

Keep at least two copies in different places — for example, the computer and a cloud drive. Test that you can restore a file before you need it.

Practice

1. Create a folder structure for your school work.
2. Rename three files with clear, dated names.
3. Explain two places you could back up an important document.

Recap

Organise files in folders, name them clearly and keep more than one backup.
