I want to delete any files inside 3 folders (their names do not change). However, these folders are inside a folder that has a variable name (created automatically). In the scenario below, L12345 is the variable name, and will always start with L, but the numbers that follow will be randomized.
In this scenario, I want to delete all files inside dir1, dir2, and dir3 which are inside the variable-ly named folder L12345.
How do I accomplish this? This will be run under Windows 7.
