XL: "Cannot Access" Error Saving File to 'C' on a Macintosh Computer

ID: Q176699

The information in this article applies to:

Microsoft Excel for the Macintosh, versions 5.0, 5.0a
Microsoft Excel 98 Macintosh Edition

SYMPTOMS

In the versions of Microsoft Excel listed at the beginning of this article, if you run a Microsoft Excel macro or a Visual Basic for Applications macro, you may receive an error message similar to either of the following:

Run-time error '1004':
Cannot access 'C'.

-or-

Run-time error '1004':
Microsoft Excel cannot access the file 'C'. There are several possible reasons:

The file name or path name does not exist.

The file you're trying to open is being used by another program.

Close the document in the other program, and try again.

The name of the workbook you're trying to save is the same as the name of another document that is read-only. Try saving the workbook with a different name.

CAUSE

This problem may occur if the macro contains code that saves a workbook by using an MS-DOS path and file name, as in the following examples:


   =SAVE.AS("C:\Data\Test.xls")
 
   ActiveWorkbook.SaveAs "C:\Data\Test.xls"

To work around this problem, make sure that your macro is designed to account for differences between the Microsoft Windows and Macintosh operating systems.

One way to do this is to use the Application.OperatingSystem property to determine whether you are on a computer running Windows or on a computer running the Macintosh operating system, for example:


      Sub CheckOS()

       ' OS equals "Mac" if this is a Macintosh, "Win" if this is a
       ' computer running Windows or Windows NT.
       OS = Left(Application.OperatingSystem, 3)

       If OS = "Win" Then

           ' Use a valid Windows path.
           ActiveWorkbook.SaveAs "C:\Data\Test.xls"

       ElseIf OS = "Mac" Then

           ' Use a valid Macintosh path.
           ActiveWorkbook.SaveAs "Data:Test.xls"

       End If

   End Sub

If you are using the Microsoft Excel (XLM) macro language, the code to use is the following:


   OS=LEFT(GET.WORKSPACE(1),3)
   =IF(OS="Win")
   =SAVE.AS("C:\Data\Test.xls")
   =ELSE.IF(OS="Mac")
   =SAVE.AS("Data:Test.xls")
   =END.IF()
   =RETURN()

STATUS

This behavior is by design of the versions of Microsoft Excel listed at the beginning of this article.

MORE INFORMATION

In Microsoft Windows and Microsoft Windows NT, path names for files include both colons (:) and backslashes (\), for example:

C:\Data\Test.xls

The colon separates the disk drive letter from the remainder of the path, which uses backslashes to separate folder names from the file name.

On the Macintosh, path names for files use only colons, for example:

Data:Test.xls

If you attempt to use a MS-DOS file name in a macro on the Macintosh, you may receive an error message similar to one of those in the "Symptoms" section in this article. This behavior occurs because the folder name "C" (from "C:\Data\Test.xls") usually does not exist on a hard disk on a Macintosh computer.
