Cannot open Office document because the path is too long

This issue occurs because of a character limit on creating and saving files in Office products. This issue occurs if the path of the file that you open or save meets the following condition:

• Microsoft Word, Microsoft PowerPoint, and Microsoft Access: The total length of the path and the file name, including file name extension, exceeds 259 characters.
• Microsoft Excel: The total length of the path and the file name, including file name extension, exceeds 218 characters.

Note: This limit includes the three characters that represent the drive, the characters in folder names, backslash characters between folder names, and the characters in the file name itself.
 
Workaround: To work around this issue, try any of the following:

• Reduce the character count
• 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.
• Move the file to a folder that has a shorter path name.
