Use the Change event to notify your application whenever the browsed folder's content has been changed, like adding or removing files. The Change event is fired only if the AutoUpdate property is True, and ChangeNotification property is True. Use the State property to determine the new state of the file or folder. Use the Folder property to specify whether the object holds information about a folder of a file. Use the BrowseFolderPath property to indicates the browsed folder. Use the Item property to access a file giving its index in the Files collection. Use the Count property to retrieve the number of File objects in the Files collection.

The following VB sample displays the files that have been changed in the browsed folder:

Private Sub ExFileView1_Change(ByVal Files As EXFILEVIEWLibCtl.IFiles)
    Dim f As EXFILEVIEWLibCtl.File
    For Each f In Files
        Debug.Print "'" & f.Name & "' " & IIf(f.Folder, "foder", "file") & " " & IIf(f.State = Added, "added", IIf(f.State = Changed, "changed", IIf(f.State = Deleted, "deleted", "unchanged")))
    Next
End Sub

Open a new Windows Explorer instance that browses the same folder as your control. Add new folders, remove folders, or change regular files. Your VB output should look like the following:

The 'New Folder (2)' foder - Added
The 'New Folder (2)' foder - Deleted
The 'New Folder' foder was deleted
The 'New Text Document.txt' file was added
The 'New Text Document.txt' file was changed

The following C++ sample displays the files that have been changed in the browsed folder:

#include "Files.h"
#include "File.h"
void OnChangeExfileview1(LPDISPATCH Files) 
{
	CFiles files( Files ); files.m_bAutoRelease = FALSE;
	for ( long i = 0; i < files.GetCount(); i++ )
	{
		CFile1 file = files.GetItem( COleVariant( long( i ) ) );
		CString strState;
		switch ( file.GetState() )
		{
			case 0: 
			{
				strState = "unchanged";
				break;
			}
			case 1: 
			{
				strState = "changed";
				break;
			}
			case 2: 
			{
				strState = "added";
				break;
			}
			case 3:
			{
				strState = "deleted";
				break;
			}
		}
		CString strOutput;
		strOutput.Format( "'%s' %s %s\n", file.GetName(), (file.GetFolder() ? "folder" : "file" ), strState );
		OutputDebugString( strOutput );
	}
}

The following VB.NET sample displays the files that have been changed in the browsed folder:

Private Sub AxExFileView1_Change(ByVal sender As Object, ByVal e As AxEXFILEVIEWLib._IExFileViewEvents_ChangeEvent) Handles AxExFileView1.Change
    Dim f As EXFILEVIEWLib.File
    For Each f In e.files
        Debug.WriteLine("'" & f.Name & "' " & IIf(f.Folder, "foder", "file") & " " & IIf(f.State = EXFILEVIEWLib.ChangeEnum.Added, "added", IIf(f.State = EXFILEVIEWLib.ChangeEnum.Changed, "changed", IIf(f.State = EXFILEVIEWLib.ChangeEnum.Deleted, "deleted", "unchanged"))))
    Next
End Sub

The following C# sample displays the files that have been changed in the browsed folder:

private void axExFileView1_Change(object sender, AxEXFILEVIEWLib._IExFileViewEvents_ChangeEvent e)
{
	for (int i = 0; i < e.files.Count; i++)
	{
		EXFILEVIEWLib.File file = e.files[i];
		string strOutput = "'" + file.Name + "' ";
		strOutput += (file.Folder ? "folder" : "file") + " ";
		strOutput += (file.State == EXFILEVIEWLib.ChangeEnum.Added ? "added" : (file.State == EXFILEVIEWLib.ChangeEnum.Deleted ? "deleted" : (file.State == EXFILEVIEWLib.ChangeEnum.Changed ? "changed" : "unchanged")));
		System.Diagnostics.Debug.WriteLine(strOutput);
	}
}

The following VFP sample displays the files that have been changed in the browsed folder:
