vscode hang when try to delete a large directory

[ladyrick]

Type: Bug

I have a directory about 100000 files total 3T size. When I right click it and select "delete permanently", vscode terminal get hang. And later, remote ssh connection is broken. I then reload vscode and vscode told me it cannot save the editing file.

I searched github issues. All related issues are closed. The earliest issue even go to 2018. But now I still got this issue.

The most thing confusing me is that, why can't vscode just rm -rf the directory in the background? What is vscode doing when it hangs?

I tried to rm -rf the directory in terminal. It also takes some time, but other part of vscode works well.

Also, rename a folder in vscode can be very slow depending on how many files in the folder. But in the terminal, rename a folder finished instantly.
