It's an abbreviation of Error NO ENTry (or Error NO ENTity), and can actually be used for more than files/directories.
它是 Error NO ENTry（或 Error NO ENTity）的缩写，实际上不仅可以用于文件/目录。
It's abbreviated because C compilers at the dawn of time didn't support more than 8 characters in symbols.
它被缩写是因为早期的 C 编译器不支持超过 8 个字符的符号。

It's simply “No such directory entry”. Since directory entries can be directories or files (or symlinks, or sockets, or pipes, or devices), the name ENOFILEwould have been too narrow in its meaning.
它只是“没有这样的目录条目”。由于目录条目可以是目录或文件（或符号链接、套接字、管道或设备），因此该名称ENOFILE的含义过于狭窄。
