Extension topic The file extension, also known as the suffix of the file, is a mechanism used by the operating system to identify the file type. Normally, an extension follows the main file name, separated by a delimiter. In a file name like "readme.txt", readme is the main file name, and txt is the extension (text, full name in foreign language: Text), indicating that the file is considered a plain text file. The extension can be thought of as metadata for a type. Huajun Software Park provides extension topics for everyone to download.
