更多细节，请参考SO上类似问题：删除构建记录时是否应删除与之关联的制品？
此外，如果您手动删除构建，则会删除所有构建内容。
更新
目前，当一个构建被删除时，服务器上的构建文件会被删除，但是存储在UNC共享中的构建文件不会被删除。这也是一个已知的问题: Build.Preview - Drop Folder not deleted when build is deleted
如果是这样，您可能需要手动删除它们。

我在想你是否混淆了工作文件夹和丢弃文件夹。默认的工作文件夹位置是代理安装目录下的一个名为"_work"的文件夹。该文件夹中的文件将保留或删除，直到下一次构建触发。您可以在构建日志中找到该目录以进行双重检查。更多详细信息，请参阅MSDN的定义。

每个代理都有自己的工作文件夹，例如XXX\Agent1、XXX\Agent2，...XXX\Agent6。我认为问题在于您混淆了文件结构。
根据您的文件结构，部署到服务器上的文件将复制到名为XXX\builds的文件夹中。然而，这些文件不是已发布的构件，而是一些类似临时文件的东西。如果您想自动删除builds下的文件，可以在最后一步添加一个删除文件任务。即使这些文件在构建过程中被删除，您仍然可以在构建完成后从服务器上下载构件。
我在这里做一个假设，即我们知道TFS2015 Update2不支持此功能且微软声称在TFS15中已解决此问题。
我将为大家粘贴整个程序。这段代码是有效的，我正在使用它。我运行此实用程序来清理已从TFS中删除的构建的构建工件放置位置。我们假设要使用两个文件夹路径调用exe：
DeleteBuild.exe "D:\TFSDropLocation" "D:\DumpFolderBeforeIDeleteThis"
TFSDropLocation 是 TFS 存放构建产物的位置，DumpFolderBeforeIDeleteThis 是我在永久删除之前收集所有构建的文件夹。我们本可以直接从 TFSDropLocation 删除它们，但我喜欢这个额外的步骤，将它们移动到另一个位置，以防万一我们需要它们，或者在进行一轮验证后从该位置删除它们 - 如果这让您感到舒适的话。
