Moving model results with CASE

You are working as a data scientist in charge of analyzing some machine learning model results. The production environment moves files into a folder called model_out/ and names them model_RXX.csv where XX is a random number related to which experiment was run.

Each file has the following structure (example):

Model Name, Accuracy, CV, Model Duration (s)
Logistic,42,4,48

Your manager has told you that recent work in the organization has meant that tree-based models are to be kept in one folder and everything else deleted.

Your task is to use a CASE statement to move the tree-based models (Random Forest, GBM, and XGBoost) to the tree_models/ folder, and delete all other models (KNN and Logistic).
