Points:
->Here dir:directory specify the directory and not considered as the root of document so if we run command  like :  xdmp:filesystem-directory("C:\ColossusImportExport\0000001\EXPORT")/dir:directory
then it returns an empty sequence.here dir:filename is the root of structure.

->the uri path  "C:\ABC\0000001\EXPORT" is case insensitive.
