"File path you entered is too long" when saving Excel file in OneDrive

Symptom

When you try to save a Microsoft Excel workbook in OneDrive, you receive the following error message:

The file path you entered is too long. Enter a shorter file name or select a shorter file path, and then try saving the file again.   

Cause

This issue occurs because the total length of the path and the file name, including the file name extension, exceeds 255 characters. 

Note

This limitation includes the characters that represent the server name, the characters in folder names, the backslash character between folders, and the characters in the file name.

Resolution

To fix the issue, make sure that the path of the file contains no more than 255 characters. To do this, use one of the following methods:

  • Rename the file so that it has a shorter name.
  • Rename one or more folders that contain the file so that they have shorter names.
  • Save the file to a folder that has a shorter path.
