Thunderbird的Nstmp文件夹

缘起
今天突然发现Thunderbird里面多了一个nstmp文件夹，看了下，好像和收件箱的内容一致。这个文件夹是干嘛的？它是如何出现的？我能不能删除它呢？一连续的问题让我去百度了一下。搜索结果里面貌似没有中文文档，也没有博客写过，也没有问答提到过。不过在mozillazine找到了一篇英文文档，标题是“Nstmp folders”，仔细看了一下，虽然没完全看懂，但大概明白了。想想，抽点时间尝试翻译一下，也是学习的一个过程，而且这里面有一些专业的计算机英语词汇，挺有意思的。最后说一下MozillaZine，它的全称是MozillaZine Knowledge Base，是为Mozilla产品提供帮助、支持、资源的“all in one place”。

This article was written for Thunderbird but also applies to Mozilla Suite / SeaMonkey (though some menu sequences may differ).
这篇文章是以Thunderbird为基础写的，但也可以应用在Mozilla Suite和SeaMonkey上面（尽管有些菜单项可能不同）
Thunderbird creates a temporary file called “nstmp” when it’s compacting a folder. If Thunderbird is interrupted during the compacting, it will abort, and the temporary file will not be deleted. If the problem occurs multiple times, you’ll see numbered files (“nstmp1″, “nstmp2″, etc.).
当Thunderbird压缩一个文件夹的时候会创建一个叫做nstmp的临时文件夹。如果压缩过程被中断，这个过程也会被终止，但是临时文件夹不会被删除。当多次被中断后，会出现顺序编号的临时文件夹，比如nstmp1、nstmp2等。
Shutting the program down during the compacting process, whether intentionally or due to a crash, will interrupt the process. Receiving a new message in the folder you’re compacting will also interrupt the process. You can avoid the problem by switching to working offline (“File -> Offline -> Work Offline”) before you compact a folder, but thats a nuisance. Usually you can prevent this problem by keeping your inbox as empty as possible (store messages in other folders/child folders) and setting “Tools -> Options -> Advanced -> Network & Disk Space -> Disk Space -> Compact disk space when it will save over” to a lower value.
无论是有意或者直接的破坏都会终止进程，进而关闭压缩文件夹的过程。当压缩的时候接收新的邮件也会出现终止进程的情况。因此在压缩文件夹之前，你可以通过（文件 -> 脱机 -> 脱机工作）设置脱机，以防止发生这种情况，确实挺麻烦的。通常你可以通过尽可能清空你的收件箱来避免出现这种情况，把邮件内容移到其他文件夹或者子文件夹内，并且把（工具 -> 设置 ->高 -> 网络&磁盘空间 -> 磁盘空间 -> 需要节省空间时压缩全部文件夹）的数值调到更小。
Check to see which folder the nstmp folder is duplicating, and check that the original folder is okay (e.g. compare number of messages in “View -> Toolbars -> Status Bar”). If so, you can delete the “nstmp” folder(s) by right-clicking it and choosing “Delete Folder” (or by deleting the files in your profile).
找到内容被复制到nstmp文件夹的是哪个文件夹，确认它是否有问题（比如邮件的压缩条数）。如果没问题，你可以通过鼠标右键的删除操作来删除nstmp文件夹。

    Thunderbird creates the “nstmp” file in the same directory as the folder it’s compacting, and then renames it. This means it’s possible that you might not be able to compact a large folder because you don’t have enough free disk space. If this occurs, try compacting some smaller folders one by one to free up enough space.
    Thunderbird在被压缩的文件夹的目录里创建nstmp文件夹，然后再重命名。这意味着因为没有足够的磁盘空间，你可能不能压缩一个大文件夹。如果发生这种情况，试试一个个的压缩更小的文件夹，从而获得足够的磁盘空间。
    A few users report a “nstmp” folder if they delete some messages, click “File -> Empty Trash” , the Trash folder for some unknown reason is no longer displayed and they compact the folders. This problem occurs regardless of whether they’re offline or not. However, if they exit Thunderbird, restart it, and the Trash folder is displayed again in the folder pane they can compact the folder with no ill side-effects.
    少量用户报告，在被压缩的文件夹里面删除某些邮件，然后点击（文件 -> 清空废件箱），这时废件箱不知什么原因会消失。无论脱机与否都会出现这种情况。当关闭Thunderbird并且重新启动后，废件箱会再次显示出来，并且可以随意的压缩文件。
