# FileLen 函数

返回文件长度，以字节为单位。

### 语法:

    FileLen (Text As String) As Long

### 返回值:

Long

Use ScriptForge.FileSystem service GetFileLen() method when size is expected to be over 2 gigabytes.

### 参数:

「Text」: 含有明确文件规格的任意字符串表达式。也可以使用 URL 表示法。

This function determines the length of a file. If the FileLen function is called for an open file, it returns the file length before it was opened. To determine the current file length of an open file, use the Lof function.
