SQL Server 2012 :: View To Concatenate File / Path Names Back To Root Directory?

We have a hierarchical table of some 2-3k of rows that grows slowly at only 3-5 rows a month, and is never likely to be above 5k, holding file/directory names with an IdParent int value pointing at that items immediate parent or NULL if root

Below is a sample:

Id Name IdParent
1 C: NULL
2 D: NULL
3 ProgramFiles 1
4 DataFiles 2
5 Excel.EXE 3
6 MyDataList.CSV 4

iterative code required to achieve the result I am looking for is best handled in the Application layer, but in this case the design brief is that we must get our results back as a View. Speed of execution and code clarity are secondary 'icing on the cake' issues.

I have tried recursive CTE's and XML FOR solutions but without success, and while I feel the latter is probably the best all rounder the searches I have made and the examples I have read do not seem to solve this particular issue.

Even to find the starting point of the search tree (i.e. the .EXE and the .CSV items) was difficult because the final slash is optional in some of the rows (.e. row 4)

The end result of my view on the above data should return:

Id FilePath
5 C:ProgramFilesExcel.EXE
6 D:DataFilesMyDataList.CSV (note the adding of the missing delimiter between DataFiles and MyDataList)
