In a loop, I test various values and depending on those values I want to add an item to either ListA or ListB.&nbsp;&nbsp; The question I have is how I can add/append an item (for example, file name as a text string) to a variable/list?

\*\*\*\*\*\*\*\*

FileList = file1.txt, file2.txt, file3.txt, file4.txt, file5.txt

Iterate FileList

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If file is of 'this type' then add NextFilename to ListA

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Else add NextFilename to ListB

\*\*\*\*\*\*\*\*

So, at the end of the iteration, ListA and ListB might look something like...

ListA: file1.txt, file3.txt

ListB: file2.txt, file4.txt, file5.txt

I will then write actions to process ListA and ListB separately as variables that I can use with the List Iterator action.&nbsp;&nbsp; I am just stuck on how to append items to a list.&nbsp;&nbsp; Suggestions please?

Hi Clive,   
  
 There’s an Append To Variable action which should do exactly what you need. :).
