FileSystem.MoveFile Method (String, String)

Moves a file to a new location.

Namespace:  Microsoft.VisualBasic.FileIO
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

public static void MoveFile(
	string sourceFileName,
	string destinationFileName


Type: System.String

Path of the file to be moved.

Type: System.String

Path of the directory into which the file should be moved.


The path is not valid for one of the following reasons: it is a zero-length string; it contains only white space; it contains invalid characters; or it is a device path (starts with \\.\); it ends with a trailing slash.


destinationFileName is Nothing or an empty string.


The source file is not valid or does not exist.


The file is in use by another process, or an I/O error occurs.


The path exceeds the system-defined maximum length.


A file or directory name in the path contains a colon (:) or is in an invalid format.


The user lacks necessary permissions to view the path.

If the target structure does not exist, it is created.

The MoveFile method preserves ACEs (Access Control Entries) only when moving the file within the same volume. This includes inherited ACEs, which become direct ACEs when moved (direct ACEs take precedence over inherited ACEs). If a file is moved between volumes, ACEs will not be copied.

The following table lists an example of a task involving the My.Computer.FileSystem.MoveFile method.

This example moves the file Test.txt from TestDir1 to TestDir2.

My.Computer.FileSystem.MoveFile("C:\TestDir1\test.txt", "C:\TestDir2\test.txt")

This example moves the file Test.txt from TestDir1 to TestDir2 and renames it Test2.txt.

My.Computer.FileSystem.MoveFile("C:\TestDir1\test.txt", "C:\TestDir2\test2.txt")
