clc://server

- refers to a data object present in a persistence model. This part of the URL is then followed by the name of the persistence model the data is located in. For example, the name of particular CLC Server File Location. An example of this form is: clc://server/CLC_Server_Project/alignments/myAlignment

Note that for CLC data in a persistence model, you need the name of the data object (as seen via the Navigation area of the Workbench) not the name of the file holding the data object (as seen when listing files using system tools like the commands ls or dir).
