Answer 1

You can try this.

SELECT REVERSE(LEFT(REVERSE(columnName),CHARINDEX('\',REVERSE(columnName))-1)) AS FileName,
REVERSE(RIGHT(REVERSE(columnName),LEN(REVERSE(columnName)) - CHARINDEX('\',REVERSE(columnName)))) AS Directory

Answer 2

An alternative to SubString would be to use the following, using CharIndex and Reverse :

Select  Left([FilePath], Len([FilePath]) - CharIndex('\', Reverse([FilePath])))     [FolderPath],
        Right('\' + [FilePath], CharIndex('\', Reverse('\' + [FilePath])) - (1))    [FileName]

This will pull everything after the last \\ as the FileName, and everything before as the FolderPath.
