Folder cannot be deleted

[ProjectRabbit-403]

I used this code in my project, which generated a folder in the project directory, but this folder cannot be deleted

//File upload
const upload = multer({dest: 'upload '});
File.post('/put',upload.single('file'),(req,res)=>{
    ...
})

Windows cannot be deleted, and neither can PowerShell

I don't know why, but VSCode can be deleted 🫤
