Hello Rob,=20

I tried :=20
zip://c:/temp/toto.zip
zip:file://c:/temp/toto.zip

But with the same exception :
org.apache.commons.vfs.FileSystemException: Could not replicate
"file://c:/temp/toto.zip" as it does not exist.

I think this is a bug in zip protocol as it tried to wrap the file =
protocol
but can't manage to do it with a -non-existant file.
Am I Wrong again :-) ?

Hang on - you've switched protocols there - You asked about "file:" urls =
not

"zip:" urls!

Looking at the vfs docs=20
(http://jakarta.apache.org/commons/sandbox/vfs/filesystems.html) it =
would
seem=20
that any of the following would refer to the file that you are after:

     file://C:/temp/toto.zip
     c:\temp\toto.zip
     c:/temp/toto.zip

Note that the url version uses '/' symbols not '\' from your example.

If you want to use the zip protocol then you need to wrap a file url, =
and=20
usually refer to an entry within the zip: (I'm not sure what you get =
without

referring to an entry)
     zip:file://C:/temp/toto.zip

Hope that helps,

Rob
