File System and Extensions
A file system is a directory that contains other files and folders. The operating system (OS) provides a file system, which is a virtual organization of files and folders. This means that the OS does not physically store the files, but instead creates virtual references to them. This allows the OS to manage and access files quickly and efficiently.
File extensions are a way for files to be identified and sorted by the operating system. Common file extensions include ".docx", ".xlsx", and ".pdf". These extensions tell the operating system what type of file it is, such as a Word document, an Excel spreadsheet, or a PDF document.
Using the file system and extensions makes it easier for users to manage and share files. By knowing the file extension, users can open and edit files from different applications without having to guess what they are. This can save time and effort.
Examples:
A DOCX is a file created using the Microsoft Word application.
An XLSX is a file created using the Microsoft Excel application.
A PDF is a file created using Adobe Acrobat
