file types

File types refer to the formats used for storing digital data on computers, each suited for specific purposes. Common types include text files (like `.txt`), which contain plain text; image files (like `.jpg` or `.png`), used for pictures; and document files (like `.docx`), for word processing. Audio files (such as `.mp3`) are for music or sound, while video files (like `.mp4`) store moving images. Each file type has its own characteristics, such as how it is compressed or the quality of the content, allowing users to choose the appropriate format for their needs.
