Features of WebEx - or are ports just open?

Today I was using WebEx with an Engineer, and she said she would drop an file onto my C drive

Even though we were sharing screens, I could not see her drop an file onto my C drive, but when I was looking at the C drive, refreshed the screen and it appeared.

I'm kinda confused as to how she was able to do this? Is this a feature of WebEx, or should certain ports be closed? Because, if she is able to put something in my computer without my knowledge, couldn't she also copy a file without my knowledge?

It's a feature of webex -- you can share files with it.

LOL, I would be more worried if it was deleted!

Henry, You did not mention how to avoid sharing. or disable this feature.

You avoid sharing files by not sharing any. It's not like the other person can browse your hard drive and download files - only those that you choose to share are transferred.

I am on a Windows XP box, and if she wouldn't have told me that she is placing the file on my computer, I would have never known. I didn't choose to share my C drive. As a matter of fact, sharing is off by default.

So, how do I turn off this feature of sharing files, folders, drive if I allow WebEx?

You misunderstand how sharing works - there is nothing to turn off. Unless you specifically share a file with someone (by using the respective menu, or however that works), nothing is shared. The fact that someone else shares a file with you does not imply that you are sharing anything with anyone.

Tim, do you mean there is a default location where all the shared file gets stored. And may be may be the c:\ was default location on Sandra's machine where an incoming/shared file landed up.

Of course there's a default location for shared files to be downloaded to. But that doesn't mean that any files that happen to be in that directory are shared.

Now, if by default the default location is c drive or say some root drive then it is ok, else it is obvious to be suspicious.

she said and she did!
One of my professor in college used to say, "The law of networking is that one computer can not control/intrude into another without the permission of the latter."

Does java has any feautres that can do desktop sharing?
