This document provides information about different file formats and how to manage files effectively. It discusses common file extensions for documents, spreadsheets, databases, presentations, images, video, compressed files, and generic text/data files. It also explains how to use zip and rar compression to reduce file sizes for transmitting files over the internet. Key points covered include common file extensions for word documents, spreadsheets, databases and presentations. It also describes how compression works by reducing file sizes for transmission but requiring more disk space when decompressed.

9. Using zip and rar
compression

10. • All of the files and folders inside the folder you compress are
compressed.
• When files are compressed the size of the file is reduced, so less
time is needed to transmit them across the internet. When files
are decompressed, they will need more disk space again.
