D:\inetpub\wwwroot\July-2016\overview\05572YEF5.pdf D:\inetpub\wwwroot\July-2016\overview\45083AFX5.pdf D:\inetpub\wwwroot\July-2016\overview\46176PFG5.pdf D:\inetpub\wwwroot\July-2016\overview\38148DLN2.pdf D:\inetpub\wwwroot\July-2016\overview\38148DLQ5.pdf D:\inetpub\wwwroot\July-2016\overview\94986TA23.pdf D:\inetpub\wwwroot\March-2016\overview\FocusList.pdf D:\inetpub\wwwroot\March-2016\overview\38148DHS6.pdf D:\inetpub\wwwroot\March-2016\overview\38148DHK3.pdf D:\inetpub\wwwroot\March-2016\overview\38148DHV9.pdf

I want to create the seperate lists for both, now tthere is a small catch. the July-2016 and March-2016 will be dynamic values i mean they can from jan or feb or 2015 so a single can contain multiple month and years combination.

i want them to be created as seperate lists so i can use them

how can i do, i tried few of the functions like listvenn or listcompare, none seems to matching what i am trying to do here from cflib

You want to create two lists based on the value of the month-year?

First, loop through the file paths and pull out the fourth value which is the month/year
Create a structure whose elements are those dates, then add the file path to that structure.

<cfset newList = structNew()>
<cfloop index="aPath" list="#string#" delimiters=" ">
   <cfset theDate = listGetAt(aPath,4,"\/")>
   <cfif NOT structKeyExists(newList,theDate)>
      <cfset newList[theDate] = thePath>
   <cfelse> <!---- key already exists ---->
      <cfset newList[theDate] = listAppend(newList[theDate],thePath," ")>
   </cfif>
</cfloop>

<cfdump var="#newList#">

the string is the list of paths you have.

ThePath is a type o, it is the same variable in the index

<cfset newList = structNew()>
<cfset theString = "D:\inetpub\wwwroot\July-2016\overview\05572YEF5.pdf D:\inetpub\wwwroot\July-2016\overview\45083AFX5.pdf D:\inetpub\wwwroot\July-2016\overview\46176PFG5.pdf D:\inetpub\wwwroot\July-2016\overview\38148DLN2.pdf D:\inetpub\wwwroot\July-2016\overview\38148DLQ5.pdf D:\inetpub\wwwroot\July-2016\overview\94986TA23.pdf D:\inetpub\wwwroot\March-2016\overview\FocusList.pdf D:\inetpub\wwwroot\March-2016\overview\38148DHS6.pdf D:\inetpub\wwwroot\March-2016\overview\38148DHK3.pdf D:\inetpub\wwwroot\March-2016\overview\38148DHV9.pdf">
<cfloop index="aPath" list="#theString#" delimiters=" ">
   <cfset theDate = listGetAt(aPath,4,"\/")>
   <cfif NOT structKeyExists(newList,theDate)>
      <cfset newList[theDate] = aPath>
   <cfelse> <!---- key already exists ---->
      <cfset newList[theDate] = listAppend(newList[theDate],aPath," ")>
   </cfif>
</cfloop>

<cfdump var="#newList#">
