Auto Detect File Name + Renaming + Copy File - in Subfolder

Hello, the following feauture I need: 1. Rename all Files in SUBFOLDER of C:\files that includes the word "setup" and is a .exe / . msi Example: In C:\Data\Subfolder\[login to view URL] -> Rename to "xyz" Or C:\Data\Subfolder\[login to view URL] -> Rename to "abc" 2. After all Subfolder exe / msi - Setup Files are renamed, the Program has to copy a New file to the Setup. The file that has to be copied shall be choosed randomly from a directory. Example: If "renaming" is finshed, then: Copy random file from "C:\RandomFilesHere\" to the "Subfolder" where the file was renamed in point 1. Note: the subfolder name has to be detected, the name of that subfolder is always different. All in all in easy task I think :)
