FileSystem.FileLen(String) Method

Definition

Returns a Long value that specifies the length of a file in bytes. The My feature gives you better productivity and performance in file I/O operations than FileLen. For more information, see GetFileInfo(String).

public static long FileLen (string PathName);
Parameters
PathName
String

Required. String expression that specifies a file. PathName may include the directory or folder, and the drive.

Returns

Long value that specifies the length of a file in bytes.

Exceptions

File does not exist.

Examples

This example uses the FileLen function to return the length of a file in bytes. For purposes of this example, assume that TestFile is a file that contains some data.

Dim MySize As Long
' Returns file length (bytes).
MySize = FileLen("TESTFILE")

Remarks

If the specified file is open when the FileLen function is called, the value returned represents the size of the file at the time it was opened.

Note

To obtain the current length of an open file, use the LOF function.
