How to rename file in Install4j? -

How can I change the file name in install4j?

I have a step to choose the file by the user, and if the user uploads the file in different names then x.txt exts me some post action

It needs to be renamed with. See if install4j has the option of transferring files and directories, but I see only destination as a folder, not a file name.

I see only one way that how to actually change the file name by creating "run script" post action and writing code in java.

Is there any other standard option in this to install4j?

If the "source files or directories" "move files and directories" the action set in a file The "destination directory" property can also be a filename and then the name of the file name will change.
