File.Move(String, String) File.Move(String, String) File.Move(String, String) File.Move(String, String) Method

Definition

Moves a specified file to a new location, providing the option to specify a new file name.

public:
 static void Move(System::String ^ sourceFileName, System::String ^ destFileName);
public static void Move (string sourceFileName, string destFileName);
static member Move : string * string -> unit
Public Shared Sub Move (sourceFileName As String, destFileName As String)

Parameters

sourceFileName
String String String String

The name of the file to move. Can include a relative or absolute path.

destFileName
String String String String

The new path and name for the file.

Exceptions

The destination file already exists.

-or-

sourceFileName was not found.

sourceFileName or destFileName is a zero-length string, contains only white space, or contains invalid characters as defined in InvalidPathChars.

The specified path, file name, or both exceed the system-defined maximum length.

The path specified in sourceFileName or destFileName is invalid, (for example, it is on an unmapped drive).

sourceFileName or destFileName is in an invalid format.

Examples

The following example moves a file.

using namespace System;
using namespace System::IO;

int main()
{
   String^ path = "c:\\temp\\MyTest.txt";
   String^ path2 = "c:\\temp2\\MyTest.txt";
   try
   {
      if (  !File::Exists( path ) )
      {
         
         // This statement ensures that the file is created,
         // but the handle is not kept.
         FileStream^ fs = File::Create( path );
         if ( fs )
                  delete (IDisposable^)fs;
      }
      
      // Ensure that the target does not exist.
      if ( File::Exists( path2 ) )
            File::Delete( path2 );
      
      // Move the file.
      File::Move( path, path2 );
      Console::WriteLine( "{0} was moved to {1}.", path, path2 );
      
      // See if the original exists now.
      if ( File::Exists( path ) )
      {
         Console::WriteLine( "The original file still exists, which is unexpected." );
      }
      else
      {
         Console::WriteLine( "The original file no longer exists, which is expected." );

Remarks

This method works across disk volumes, and it does not throw an exception if the source and destination are the same. Note that if you attempt to replace a file by moving a file of the same name into that directory, you get an IOException. You cannot use the Move method to overwrite an existing file.

The sourceFileName and destFileName arguments can include relative or absolute path information. Relative path information is interpreted as relative to the current working directory. To obtain the current working directory, see GetCurrentDirectory.

If you try to move a file across disk volumes and that file is in use, the file is copied to the destination, but it is not deleted from the source.
