OFF97: Kill Statement May Delete All Files in a Folder

• Microsoft Office 97 for Windows
• Microsoft Excel 97 for Windows
• Microsoft Word 97 for Windows
• Microsoft Access 97
• Microsoft PowerPoint 97 for Windows

SYMPTOMS

In any of the programs listed at the beginning of this article, if you run a Visual Basic for Applications macro that includes the Kill statement, the macro may delete all of the files stored in a folder on a network server.

CAUSE

This behavior may occur when all of the following conditions are true:

• A drive letter is mapped to a folder on a network server.

      -and-
  

• The network server is running Microsoft Windows NT Server, version 3.51 or 4.0, or Microsoft Windows NT Workstation, version 3.51 or 4.0.

      -and-
  

• The current directory is the root directory of the mapped network drive.

      -and-
  

• You use syntax for the Kill statement that is similar to either of the following

        Kill ""
  

        -or-
  

        Kill <FileList>
  

  where <FileList> is a variable that refers to nothing (""), a variable that is uninitialized, or a variable that refers to a path that does not include a file name.

The Visual Basic procedures in this article are provided 'as is' and Microsoft does not guarantee that they can be used in all situations. While Microsoft support engineers can help explain the functionality of a particular macro, they will not modify these examples to provide added functionality, nor will they help you construct macros to meet your specific needs. If you have limited programming experience, you may want to consult one of the Microsoft Solution Providers. Solution Providers offer a wide range of fee-based services, including creating custom macros.

To prevent files from being deleted by the Kill statement, verify that the Kill statements always refer to both a valid path and a valid file name. The following examples demonstrate the syntax to use:

   Kill "\\server\share\myfiles\*.old"

   Kill "E:\myfiles\*.old"

   Dim FileList As String
   FileList = "*.old"
   Kill "\\server\share\myfiles\" & FileList

   Dim FileList As String, NetPath As String
   NetPath = "\\server\share\myfiles\"
   FileList = "*.old"
   Kill NetPath & FileList

You can also prevent this problem from occurring by making sure that there are no drive letters that are mapped to shares on the network server. The problem occurs only if a drive letter is mapped to the server.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The Kill statement in Visual Basic for Applications allows you to delete files from a disk. The syntax is as follows:

   Kill <pathname>

If you want to delete all of the files in a folder, make sure that the path name that is used by the Kill statement ends in "*.*." For example, to delete all of the files in the folder E:\myfiles, you could use the following code:

   Kill "E:\myfiles\*.*"

   -or-

   Dim FileList As String
   FileList = "*.*"
   Kill "E:\myfiles\" & FileList

   Kill ""

   Kill "\\server\share\"

   Kill "\\server\share\myfiles\"

   Kill "E:\"

   Kill "E:\myfiles\"

   Dim FileList As String
   Kill FileList

   Dim FileList As String
   Kill "\\server\share\myfiles\" & FileList

   Run-time error '53':
   File not found
