Probably the easiest way to get what you want is to change the name of the .txt file in the FindChangeSupport folder to something else ... like "FindChangeList_original.txt" Then FindChangeByList.jsx won't find it right away, and will put up the File.openDialog invitation to "Choose the file containing your find/change list". You can choose any file anywhere on your computer at that point ... just navigate to where the file is ... on your desktop, in your user folder, wherever. Or, if you want to use the original txt file, choose "FindChangeList_original.txt".
Thanks, moving the folder to User worked and I've added my own searches. Very easy, simple solution--thanks!
