Probably, because it is almost precisely what the name promisses:

   a "view" on a filesystem directory.

It sees objects based on registered extensions (registered
via "registerFileExtension(extension, class)"). The registration
also defines the class, the file is mapped to.

There is an additional feature: if there is a "file.metadata" file,
then its content (format seen in the tests ".../CMFCore/tests/*/*/*.metadata")
defines metadata for "file".

Probably not. Zope will not let you change objects via this
view.

The last feature is not supported by "FSDV" (also, you can
implement it yourself).
