Windows: Explorer 'Quick Access' polluted with deleted folders inside .rustup

[oberrich]

Verification

• I searched for recent similar issues at https://github.com/rust-lang/rustup/issues?q=is%3Aissue+is%3Aopen%2Cclosed and found no duplicates.
• I am on the latest version of Rustup according to https://github.com/rust-lang/rustup/tags and am still able to reproduce my issue.

Problem

I don't know what exactly caused this but a few weeks back my explorer's 'Quick Access' got polluted with these temp dirs inside the .rustup folder.

All of these directories cannot be removed through Windows Explorer directly, simply because they don't exist anymore.

Before this happend, I've extracted ~300K archives using the zip crate earlier that day and called fs::remove_file(path).unwrap() on files inside the newly created directory.

Steps

Unclear

Possible Solution(s)

No response

Notes

The code involved was straight forward and only involved calling standard APIs or zip/image crate functions.
I'm not sure what exactly caused this issue, may or may not be related to rustup.
