File là gì ? Khái niệm và cấu trúc của file như thế … – Web Bách Thắng


In the realm of computer usage, the term “file” is a commonly heard word. But what exactly does it mean? What purpose does it serve? And how can we utilize its structure effectively? Join us as we embark on a journey to explore the ins and outs of files.

What is a File and Its Structure?

In Vietnamese, “file” translates to “tập tin.” A file is a collection of various data information created by computer users. It allows users to store data in a simple and convenient manner.

Files are named and stored on various media such as hard disks, floppy disks, CDs, DVDs, and USB drives.

Components of a File Structure

A file structure consists of a name and an extension separated by a dot (.). The extension categorizes the file, while the name can now be of any length, even including Vietnamese characters with accents.

The extension following the dot (.) determines the format and usage of the file, based on the operating system in use. Each operating system has its own rules for file extensions, rendering them incompatible with other operating systems. For example, a text document file cannot be used as audio files on software.

Different files with the same purpose may have different extensions, depending on the manufacturer or creator of the file. The context of usage and the location of the file play a role as well. Some files are designed to run specifically on certain software, while others may be used to repair other files internally.

For instance, a file with the extension .doc can only be used with Microsoft’s utility software for reading and writing text. Similarly, files with extensions such as .mp4, .mp3, .gp, .avi, etc., are recognized as audio and video files that can only run on specific audio and video playback software, not on Microsoft Word or Excel.

Characteristics of a File

A file can contain no information other than the file name itself. This is because the file name inherently holds information. Files of this nature are referred to as “empty” files.

The size of a file depends on the processing power of your computer, the operating system you are using, and the software that created it. The units of size measurement for files are kilobytes (kb), megabytes (MB), and gigabytes (GB). The conversion formula is as follows: 1024kb = 1MB and 1024MB = 1GB.
