100% CPU with explorer and code moving files to folders

Issue Type: <b>Bug</b> I wrote a simple python script to move 15k pdf's into a folder based on theri name. This pinned my CPU to 100% and slowed the process way down since the explorer window was trying to keep up with the changes I suspect. Running this with vscode closed only used 13% of my system and ran much faster. ```py from pathlib import Path from sys import exit root = Path(__file__).parent for child in root.iterdir(): if child.is_dir(): continue if child.name.startswith('MRRC_'): continue if child.suffix.casefold() != '.pdf': continue folder = Path(child.name.replace(child.suffix, "")) folder.mkdir(exist_ok=True) child.rename(folder / child.name) ``` VS Code version: Code 1.67.1 (da15b6fd3ef856477bf6f4fb29ba1b7af717770d, 2022-05-06T12:37:03.389Z) OS version: Windows_NT x64 6.3.9600 Restricted Mode: No <details> <summary>System Info</summary> |Item|Value| |---|---| |CPUs|Intel(R) Xeon(R) Gold 6240 CPU @ 2.60GHz (2 x 2594)| |GPU Status|2d_canvas: unavailable_software<br>canvas_oop_rasterization: disabled_off<br>direct_rendering_display_compositor: disabled_off_ok<br>gpu_compositing: disabled_software<br>multiple_raster_threads: disabled_off<br>oop_rasterization: disabled_off<br>opengl: disabled_off<br>rasterization: disabled_software<br>raw_draw: disabled_off_ok<br>skia_renderer: enabled_on<br>video_decode: disabled_software<br>video_encode: disabled_software<br>vulkan: disabled_off<br>webgl: unavailable_software<br>webgl2: unavailable_software| |Load (avg)|undefined| |Memory (System)|8.00GB (3.86GB free)| |Process Argv|. --crash-reporter-id 98dd838a-6bce-406d-afd2-5fcb572467ec| |Screen Reader|no| |VM|100%| </details><details><summary>Extensions (14)</summary> Extension|Author (truncated)|Version ---|---|--- vscode-json|and|1.5.2 EditorConfig|Edi|0.16.4 vscode-diff|fab|1.4.2 rainbow-csv|mec|3.2.0 xml-format|mik|1.1.3 python|ms-|2022.8.1 vscode-pylance|ms-|2022.11.10 jupyter|ms-|2022.4.1021342353 jupyter-keymap|…
