100% CPU with explorer and code moving files to folders

See original GitHub issue

Issue Type: Bug

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.

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)

@steveoh ok good, that window process has tooling to profile it to see where time is spend, can you follow https://github.com/Microsoft/vscode/wiki/Performance-Issues#profiling-the-renderer-process and attach?
