Copying items to and from a local folder

In This Topic

Items can be copied or moved from one location to another using the CopyTo, CopyFilesTo, MoveTo, or MoveFilesTo methods. With the Xceed FileSystem, a folder is a folder regardless of if it is located on a local disk, in a zip file, in memory, or on an FTP server.

The following example demonstrates how to copy files from one local folder to another using the steps listed below:

Create an instance of a DiskFolder which will represent the source folder from which to retrieve the files.
Create an instance of a DiskFolder which will represent the destination folder where the files will be copied to.
Call the source folder's CopyFilesTo method to copy the files to the destination folder.

VB.NET Copy Code

VB.NET	Copy Code
`Imports Xceed.FileSystem` Dim source As New DiskFolder( "c:\source" ) Dim destination As New DiskFolder( "c:\destination" ) source.CopyFilesTo( destination, True, True )

Imports Xceed.FileSystem

Dim source As New DiskFolder( "c:\source" )
Dim destination As New DiskFolder( "c:\destination" )

source.CopyFilesTo( destination, True, True )

C# Copy Code

C#	Copy Code
`using Xceed.FileSystem;` `DiskFolder source = new DiskFolder( @"c:\source" ); DiskFolder destination = new DiskFolder( @"c:\destination" ); source.CopyFilesTo( destination, true, true );`

using Xceed.FileSystem;

DiskFolder source = new DiskFolder( @"c:\source" ); DiskFolder destination = new DiskFolder( @"c:\destination" ); source.CopyFilesTo( destination, true, true );

Events

All methods exposed by the Xceed FileSystem's FileSystemItem, AbstractFolder, AbstractFile, and derived classes have an overload that can be used when events are required. Events can be handled by creating an instance of the FileSystemEvents class and subscribing to the desired events. For example:

VB.NET Copy Code

VB.NET	Copy Code
Imports Xceed.FileSystem Dim source As New DiskFolder( "c:\source" ) Dim destination As New DiskFolder( "c:\destination" ) Dim events As New FileSystemEvents AddHandler events.ItemException, AddressOf Me.item_exception source.CopyFilesTo( events, Nothing, destination, True, False) RemoveHandler events.ItemException, Addressof Me.item_exception Private Sub item_exception( ByVal sender As Object, ByVal e As ItemExceptionEventArgs ) If TypeOf e.Exception Is ItemAlreadyExistsException Then e.TargetItem.Delete() e.Action = ItemExceptionAction.Retry End If End Sub


Imports Xceed.FileSystem

Dim source As New DiskFolder( "c:\source" )
Dim destination As New DiskFolder( "c:\destination" )

Dim events As New FileSystemEvents
AddHandler events.ItemException, AddressOf Me.item_exception

source.CopyFilesTo( events, Nothing, destination, True, False)

RemoveHandler events.ItemException, Addressof Me.item_exception

Private Sub item_exception( ByVal sender As Object, ByVal e As ItemExceptionEventArgs )
   If TypeOf e.Exception Is ItemAlreadyExistsException Then
      e.TargetItem.Delete()
      e.Action = ItemExceptionAction.Retry
   End If
End Sub

C# Copy Code

C#	Copy Code
`using Xceed.FileSystem;` DiskFolder source = new DiskFolder( @"c:\source" ); DiskFolder destination = new DiskFolder( @"c:\destination" ); FileSystemEvents events = new FileSystemEvents() events.ItemException += new ItemExceptionEventHandler this.item_exception source.CopyFilesTo( events, null, destination, true, false ); events.ItemException -= new ItemExceptionEventHandler this.item_exception private void item_exception( object sender, ItemExceptionEventArgs e ) { if( e.Exception is ItemAlreadyExistsException ) { e.TargetItem.Delete(); e.Action = ItemExceptionAction.Retry; } }

using Xceed.FileSystem;

DiskFolder source = new DiskFolder( @"c:\source" ); DiskFolder destination = new DiskFolder( @"c:\destination" ); FileSystemEvents events = new FileSystemEvents() events.ItemException += new ItemExceptionEventHandler this.item_exception source.CopyFilesTo( events, null, destination, true, false ); events.ItemException -= new ItemExceptionEventHandler this.item_exception private void item_exception( object sender, ItemExceptionEventArgs e ) { if( e.Exception is ItemAlreadyExistsException ) { e.TargetItem.Delete(); e.Action = ItemExceptionAction.Retry; } }

Things to consider

Do you want to filter (specify specific files and folders) the items that are to be copied? Use filters.
Do you want to display progress information? Create an instance of the FileSystemEvents class and handle the ByteProgression and/or ItemProgression events.
Do you want to display progress information when a folder is being scanned? Create an instance of the FileSystemEvents class and handle the ScanningFolder event.
Do you want to intervene when an error occurs with one or more of the items being manipulated? Create an instance of the FileSystemEvents class and handle the ItemException event.
