VSTS Release Failing due to file in use on remote server

Question

Before I state the question I am aware this may be more of a server administration question however I am seeking an answer that involves fixing / modifying the VSTS release process instead of dealing with server permissions (I don't believe this is a server issue).

I have a VSTS Build definition and Release definition. The release definition copies the files from the build to a remote server (an IIS site).

My problem is that this process fails roughly 60% of the time.

Log files showing failure error:

I circumvate the problem by manually remoting into the server and deleting the contents of the target directory manually. I've discovered that each time the release is failing, my manual delete causes a warning to popup that an .exe file is being used by another process. My suspicion is that this is the reason the release is failing.

Is there some extra step that can be added to a release to force delete / clear the target directory?

您可以使用Windows Machine File Copy任务将文件从构建复制到远程服务器。并选择清理目标，以便在将文件复制到远程服务器之前，它将首先清理目标目标文件夹。
