CAUSE

This error message occurs when you save or open a file if the path to the file (including the file name) exceeds 218 characters. This limitation includes three characters representing the drive, the characters in folder names, the backslash character between folders, and the characters in the file name.

This behavior is based on a 256-character limitation in Excel for creating links to another file. This limit of 218 characters for the path name is based on the following:

Up to 31 characters in a sheet name.
Apostrophes and brackets used to denote the workbook name.
An exclamation point.
A cell reference.

For example, the path for a file might be:

   'c:\excel\personal\...\[my workbook.xls]up_to_31_char_sheetname'!$A$1

THINGS TO TRY

Make sure that the path to the file contains fewer than 219 characters. You can do this by using one of the following methods:

Rename the file so that it has a shorter name.

-or-
Rename one or more folders that contain the file so that they have shorter names.

-or-
Move the file to a folder with a shorter path name.

MORE INFORMATION

Note that if you enter 255 characters in the File Name box in the Save As dialog box, and click OK, you will receive the following error message:

The path you entered, "<path>", is too long. Enter a shorter path.

Also, if you attempt to save a file and the path exceeds 255 characters, you will receive the following error message:

The file could not be accessed. Try one of the following:

- Make sure the specified folder exists.
- Make sure the folder that contains the file is not read-only.
- Make sure the file name does not contain any of the following characters: < > ? [ ] : | *.
