Just in case anyone might find this of interest I finally found a way, thanks to Maureen in another thread, to attach a UUID or unique file ID to the multipart upload form fields in the Plupload jQuery uploader queue widget implementation. Thanks to an article I found by Ben Nadel (http://www.bennadel.com/blog/2506-storing-per-file-multipart-params-in-the- plupload-queue.htm) I was able to hook into the widget events and inject new multi-part parameters for each file in the queue and then write them on the server using the UUID as a file name, check to see if another file of the same name exists and re-name the new file with an incremented file name. Here is the JS for the PLupload queue widget: (note the uuid(); function script is in my other post) // Retrieving a reference to plupload.Uploader object var uploader = $('#uploader').pluploadQueue(); uploader.bind('BeforeUpload', function(up) { up.settings.multipart_params.fileuuid = uuid(); }); And on the server side: <cfif FileExists("#chunkdir##trim(form.name)#")> <!--- // add an increment to the file until we find one ---> <cfset flext=listlast(trim(form.name),".")> <cfset flname=mid(trim(form.name),1,Len(trim(form.name))-len(flext))> <cfset index=1> <cfset IsFile=1> <cfloop condition="IsFile eq 1"> <cfset newname=flname & "("& index &")" & "." & flext> <cfif FileExists("#chunkdir##trim(newname)#")> <cfset IsFile=1> <cfelse> <cffile action="RENAME" source="#chunkdir##trim(form.fileuuid)#" destination="#chunkdir##newname#"> <cfset IsFile=0> </cfif> <cfset index=index+1> </cfloop> <cfelse> <cffile action="RENAME" source="#chunkdir##trim(form.fileuuid)#" destination="#chunkdir##trim(form.name)#"> </cfif> This will NOT work with the Jquery UI widget implementation since they don't seem to (easily) expose the events needed like 'BeforeUpload'.
