<p class="MsoNormal"><span style="font-size:11pt;font-family:"calibri","sans-serif";color:rgb(31,73,125)"> Thanks for getting back on this. I am trying to see how gfid can be generated programmatically. Given a file name how do we generate gfid for
it. I was reading some of the email threads about it where it was mentioned that gfid is generated based upon parent directory gfid and the file name. Given a same parent gfid and file name do we always end up with the same gfid.
