FileCopy Function

Visual Studio 2008

Copies a file.

The My.Computer.FileSystem Object gives you greater productivity and performance in file I/O operations than FileCopy. See My.Computer.FileSystem.CopyFile Method for more information.

Copy

Public Sub FileCopy( _
   ByVal Source As String, _
   ByVal Destination As String _
)

Parameters

Source: Required. String expression that specifies the name of the file to be copied. Source may include the directory or folder, and drive, of the source file.
Destination: Required. String expression that specifies the target file name. Destination may include the directory or folder, and drive, of the destination file.

Exceptions

Exception type	Error number	Condition
ArgumentException	52	Source or Destination is invalid or not specified.
IOException	55	File is already open.
FileNotFoundException	53	File does not exist.

See the "Error number" column if you are upgrading Visual Basic 6.0 applications that use unstructured error handling. (You can compare the error number against the Number Property (Err Object).) However, when possible, you should consider replacing such error control with Structured Exception Handling Overview for Visual Basic.

Remarks

If you try to use the FileCopy function on a currently open file, an error occurs.

FileCopy requires full trust to work on the local drive.

Example

This example uses the FileCopy function to copy one file to another. For purposes of this example, assume that SrcFile is a file containing some data.

Copy

Dim SourceFile, DestinationFile As String
SourceFile = "SRCFILE"   ' Define source file name.
DestinationFile = "DESTFILE"   ' Define target file name.
FileCopy(SourceFile, DestinationFile)   ' Copy source to target.
