fájlnév

A fájlnév, or filename in English, is a unique identifier assigned to a file stored on a computer or other digital storage device. It is a crucial element for organizing and accessing digital information. A filename typically consists of a name and an extension, separated by a dot. The name part is chosen by the user or the software that created the file, and it usually describes the file's content or purpose. The extension, on the other hand, indicates the file type and is often automatically assigned by the operating system or application. For example, in the filename "document.txt", "document" is the name and ".txt" is the extension, indicating it's a plain text file.

Filenames are subject to certain rules and restrictions depending on the operating system being used. These rules often dictate which characters are allowed in a filename, such as letters, numbers, underscores, and hyphens, while disallowing characters like slashes or colons that have special meaning within the file system. Filename length can also be a limitation. Case sensitivity, where "File.txt" and "file.txt" are treated as distinct, also varies by operating system. Proper naming conventions and consistent organization of filenames are essential for efficient file management and retrieval. Without clear and descriptive filenames, locating specific files within a large collection can become a difficult and time-consuming task.
