Adding a Part - The path is not of a legal form

I am trying to create and save a Part in Part maintenance and am getting an error message that “The path is not of a legal form”. Does anyone have any ideas on what I can do? Trying to save a new Customer does the same thing but I can enter a new order or a new quote.

The path is not of a legal form.

This does not look like an Epicor out-of-the-box Error. It is typically a C# Error when you are trying to write to a file and the path is invalid.

You probably have some BPMs or Customizations that require some field to be filled in, or are trying to write the part data out to a .csv or something.
