Use the HasCheckBox property to assign a check box for each item in your control. The control supports partial check feature ( three-states check box ) too. When partial check feature is on, the control displays a partial check box for an item that contains checked items as well as unchecked child items. Use the Checked property to check or uncheck by code a file or folder. Use the Get method  to get the collection of checked items.

The following VB sample displays the checked files and folders:

With ExFileView1.Get(CheckItems)
    Dim i As Long
    For i = 0 To .Count - 1
        With .Item(i)
            Debug.Print .Name
        End With
    Next
End With

The following C++ sample displays the checked files and folders:

CFiles files = m_fileview.GetGet( 2 /*CheckItems*/ );
for ( long i = 0; i < files.GetCount(); i++ )
	OutputDebugString( files.GetItem( COleVariant( i ) ).GetName() );

The following VB.NET sample displays the checked files and folders:

With AxExFileView1.get_Get(EXFILEVIEWLib.TypeEnum.CheckItems)
    Dim i As Integer
    For i = 0 To .Count - 1
        Debug.WriteLine(.Item(i).Name)
    Next
End With

The following C# sample displays the checked files and folders:

EXFILEVIEWLib.Files files = axExFileView1.get_Get(EXFILEVIEWLib.TypeEnum.CheckItems);
for (int i = 0; i < files.Count; i++)
	System.Diagnostics.Debug.WriteLine( files[i].Name );

The following VFP sample displays the checked files and folders:

With thisform.ExFileView1.Get( 2 ) && CheckItems
	local i
	for i = 0 to .Count - 1
		with .Item(i)
			wait window nowait .Name
		endwith
	next
EndWith
