You receive an error message when you use right bracket in text file name in Excel 2003 and earlier versions

In the versions of Microsoft Excel that are listed in the "Applies To" section, you may receive the following error message when you try to rename a sheet tab: The error message then goes on to explain potential reasons why the error is occurring.

This error message occurs if you open a text file whose name contains a right bracket character (]) and then try to rename the file's sheet tab.

To avoid this problem, make sure your text file name does not contain a right bracket character (]) before you open the file in Microsoft Excel. Preferably, the file name should also not contain a left bracket character ([).

In Excel, the left and right bracket characters ([ and ]) have special meaning. In worksheet formulas, they are used to separate the workbook name from the names of sheets contained within the workbook. For example: If you open a file whose name contains either a left or a right bracket, Excel may mishandle the file's name.

Note A file whose name contains a left bracket character but not a right bracket character should not be affected by this problem.
