XL2000: Macro Cannot Open a File That Has No Extension

In Microsoft Excel 2000, when you use a macro to open a file, the wrong file may be opened.

This may occur if the following conditions are true:

• The name of the file you are trying to open has no extension. For example, it is named "Noext".
  
  -and-
• The file you are trying to open is in the same folder as another file whose name is identical but whose name includes a recognized file extension (for example, "Noext.xls").

A Microsoft Visual Basic for Applications macro in Microsoft Excel 2000 cannot use the Workbooks.Open command to open a file with no extension if a file whose name is identical but contains a recognized extension exists in the same folder.

For this reason, Microsoft strongly recommends that you include an extension when you name your data files.

Microsoft also recommends that you include the file extension in the FileName argument of the Workbooks.Open command, if possible.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

In Microsoft Excel, you can use the Workbooks.Open command within a Visual Basic for Applications macro to open files. Usually, the command looks similar to the following: If you have a file whose name contains no extension, you can usually open it with the Workbooks.Open command. For example, the command would look like this: This command works correctly and opens the file "Noext", unless a file whose name is identical but includes a recognized file extension exists in the same folder. The following extensions are recognized by Microsoft Excel 2000: If such a file exists in the same folder as the file without an extension, that file opens instead.
