I guess the big question here is: To what extent is this a feasible 
replacement of FileDirectory and/or [Standard|CrLf|MultiByte]FileStream?

Besides that, a couple of smaller comments and questions:

* How does one convert 'D:\Squeak\3.10' to the equivalent to a 
FileDirectory? I.e., what's the equivalent to

	fd := FileDirectory on: 'D:\Squeak\3.10'.

and then (to make the example more concrete):

	(fd fileNamesMatching:'*.txt') do:[:oldName|
		newName := (oldName allButLast: 4),'.bak'.
		[oldFile := fd readOnlyFileNamed: oldName.
		newFile := fd forceNewFileNamed: newName.
		fd copyFile: oldFile toFile: newFile] ensure:[
			oldFile close.
			newFile close.
		].
	].

* What about Windows \\shares\? Many (most?) network file systems aren't 
mapped to drives any longer so the access to \\shares\ is fairly important.

* Nitpick: On Windows, FSPlatformTest>>testHome will generally fail. 
That's because the home location is different between Windows versions 
(it's C:\Documents and Settings\ on XP, C:\Users on Vista and Windows 7) 
but also because that path is localized (i.e., "Dokumente und 
Einstellungen" on a German XP variant). Your best guess (short of a 
dedicated primitive) is currenty

	(FileDirectory on: SecurityManager default untrustedUserDirectory)
		containingDirectory containingDirectory

since the untrustedUserDirectory nowadays defaults to <home>\My 
Documents\My Squeak (unless overridden).
