What is the use case for lscm changeset extract?

Question

I am trying to extract files to a local path from a changeset. I'm trying this:

c:\ws1>lscm.bat changeset extract -r local -w "ws2" -d "dir" 1111 "/p1/file.bat" "dir/p1/file.bat"

However, I get this error:

Problem running 'changeset extract':
Could not initialize data area. Directory "C:\ws1\dir\p1\" has shared ancestor "C:\ws1" and cannot be used as a shared root.

I thought I'd used this command in past with success, but perhaps I was in a sandbox already for ws1. For the life of me I can't figure out why you would use this command if you were already in a sandbox. But if I try to specify a directory outside of my current sandbox, I get this:

c:\ws1>lscm.bat changeset extract -r local -w "ws2" -d "c:\temp" 1111 "/p1/file.bat" "/p1/file.bat"
Problem running 'changeset extract':
Could not initialize data area. Directory is not shared: C:\temp

What I want to do is extract files from a changeset on the server to a non-shared filepath on my local. Is that possible? If not, what is the purpose of lscm changeset extract?

Thanks!

Andy

Update 3/20/14 -- the initial question is answered (see below) but interestingly, it seemed like it could not locate the changeset while I was in a sandbox:

Note:

c:\ws1>lscm -u y ls changes -r local -w "ws2" 1187

The -d option is used to specify the root of the shared file system i.e if you are running the command from outside the sandbox root, it should be used.
You may try

c:\ws1>lscm.bat changeset extract -r local -w "ws2" 1111 "/p1/file.bat" "c:\temp\file.bat"

So, the file file.bat will be copied to c:\temp\file.bat.
If the workspace "ws2" is loaded into c:\ws1 then, -d need not be used. If not, the location to 
which workspace is loaded must be specified with -d option.

Thank you, Karthik! That worked. I found something interesting, though. When I was in a sandbox it would not recognize the change within the changeset. Please see the additional edit in the original question. This this expected behavior?

c:\temp>lscm.bat changeset extract -r local -w "ws2" _tx8hga74EeOuEP2tHKCK0A "/build.gradle" "c:\temp\build.gradle"

The above command ran successfully. So, I think the workspace is loaded in c:\temp.
So, you might try
c:\ws1>lscm.bat changeset extract -r local -w "ws2" _tx8hga74EeOuEP2tHKCK0A "\build.gradle" "c:\ws1\build.gradle" -d "c:\temp"

It's all about the answers!
