Well...If my supplement is allowed, in my honest opinion ignoring the
existing way of Ada, "File_Name_String" is better.
(In addition, It's  welcome that UTF_8_String and UTF_16_String be new
types like Yannick says.)

File_Name_String is UTF-8 on OSX(if only using POSIX API), UTF-16 on
Windows and localized string on BSD (I18N of BSD is unique!).
And Equal_File_Names/Less_File_Names are necessity.
Ada.Directories.Name_Case_Equivalence is useless because case
insensitive rules between NTFS and NFS+ are different.

(I had implemented case insensitive rules of NFS+. It's difficult and
required the different table from UCD. NTFS is easier because
CompareString API can be used for this purpose. CoreFoundation
possibly have usable function, too. But I do not know. Anyway, these
are not portable. I want standard library wrapping these.)

It's just supposed story ignoreing existing way.
I may be satisfied if Form parameter is usable.
