Error when opening model files: The specified path, file name, or both are too long.

Product(s): WaterGEMS, WaterCAD, HAMMER
Version(s): CONNECT Edition
Area: Modeling


An error message is generated when trying to open a model: 

System.IO.PathTooLongException: The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

First, try doing a clean reinstallation of the product. 

Another thing you can try is to save the model to a shorter file path. One test you can try is copy the model files to the Documents folder or the Desktop.
