I am trying to join three tables and concat 2 different column into multiple rows

I am trying to join three tables and concatenate 2 different columns into multiple rows. I have four columns of data when I run a regular query with multiple filenames and multiple phone numbers. I want to get rid of the duplicates that result with the query.

I would like to have the id not duplicated with the different filenames concatenated into another column for id separated by commas. The same thing should be true with all the phone numbers concatenated into one row with the corresponding id and separated by comma.

I found some examples using xml path, but they were with only two tables and two columns.

Below I have the three tables, the query I have so far, and the query I wish to have. Does anyone know how to do nested xml paths while joining tables?

I found this on another post:

SELECT * 
FROM   ThisTable 
   OUTER APPLY (SELECT (SELECT SomeField + ' ' AS [data()] 
                        FROM   SomeTable 
                        WHERE  SomeTable.ID = ThisTable.ID 
                        FOR XML PATH ('')) AS ConcatenatedSomeField) A 
   OUTER APPLY (SELECT (SELECT SomeField2 + ' ' AS [data()] 
                        FROM   SomeTable 
                        WHERE  SomeTable.ID = ThisTable.ID 
                        FOR XML PATH ('')) AS ConcatenatedSomeField2) B 
   OUTER APPLY (SELECT (SELECT SomeField3 + ' ' AS [data()] 
                        FROM   SomeTable 
                        WHERE  SomeTable.ID = ThisTable.ID 
                        FOR XML PATH ('')) AS ConcatenatedSomeField3) C
