Perhaps since you are new livelink file names are objid representation to a specific action.
For eg if I have a document in livelink called MyDoc->MyDoc is the friendly representation of a link like this.
In the general properties of livelink you have a tool that allows you to capture a clean URL like this.
However if your intent is to create a UNC representation then there is a optional livelink module (free) that is called livelink WebDav.When you install and configure and get everything working you will be able to write it like this
\\mylivelinkserver\mysandboxlivelinkdav\nodes\248153
Hope that helps and was your question
In any case the livelink server knows how to take the objid and give the caller the file.
Well, if I called the wrong number, why did you answer the phone?
