Hello @Rohit Ravishankar ListFile uses last modified timestamp of files. It tracks the latest last modified timestamp to pick newly modified files since it ran before. So, if a file is added with older last modified timestamp than the one which ListFile already picked, then the file won't be picked with ListFile logic. There is an existing JIRA to discuss about the behavior [1]. Min/Max filter is used to filter-out files that is too-young (min) or too-old (max) files. Even if a file passed these condition if its last modified timestamp is older than the latest on already listed, it won't be picked. If your use-case requires processing input files in 'descending last modified timestamp ' order, then I'd recommend using GetFile (keepSourceFile = false) and PriorityAttributePrioritizer [2] combination.
