SE, thank you for your reply.
That's exactly what I was trying to find out from the very beginning, HOW can I create a folder in a location different than the original application directory of fms.
You wrote: "Since you have FMIE, you can create your own application under applications directory of FMS and you should be able to stream from that application folder."
I did not get it at all. To me it sound like I can create yet another application folder inside of the existant application folder, or, as you call it; "under applications directory of FMS", why would I create an application under already existant application directory. I am sure I just simply didn't understand the meaning of this expression, but this is exactly what I am trying to find out: HOW can I creat an additional 2 folders on my server machine, on which the fms installed, but OUTSIDE of the existant directory of FMS. One of them will be created in the Members folder, another one will be created outside of the Members folder, so, the one that in the Members folder will be accessable only to the members, and if the files will copy to their temporary Internet flies, that's ok. The other folder will be for previews, which is also ok to be copied on the viewers hard drives,
But the main question is the same: HOW can I create folders which I can have my running videos in OUTSIDE of the original fms application folder.
How else can I ask it...?
How can I create my own application folders at the places on my server machine where there are no fms application folders yet.
I feel so helpless that I can't properly express in words what I am asking. 
Quating you one more time: "Since you have FMIE, you can create your own application under applications directory of FMS and you should be able to stream from that application folder." What would be my step by step actions to do it?
And again, these new folders must be outside of the existant fms VOD, or any other fms folders.
Thank you.

When you install FMS , there is default location where "live" and "vod" applications are present and that folder is "applications" folder which you can find in <FMS Installed Location>. This "applications" is a directory where you can place your own applications, its like a repository.
Now you can configure your applications directory. I mean you can have more than one applications directory location. You just need to add one more entry seperated by semi-colon in fms.ini or in Vhost.xml.
Open fms.ini and search for VHOST.APPSDIR. By default it would be like
VHOST.APPSDIR = <FMSInstalled Directory>/applications
Edit it this way (assuming you member area folder is C:\MemberArea and preview area is C:\Preview)
VHOST.APPSDIR = <FMSInstalled Directory>\applications;C:\MemberArea;C:\Preview
So now you can connect to any of the applications which are in all these 3 folders.
I think confusion is arising in your mind because you are trying to apply concepts of Web Applications to FMS.
Like i said before, you can achieve you use case without keeping application in seperate folders and i have explained before how to achieve it in my previous replies.
