Stuff like family photos and tax returns seems obvious, but there is so much other stuff on the computer! Surely some of it needs to be backed up to, right?

Dear Backup Confused,

亲爱的备份感到困惑，

You’re not alone in your confusion. Copying the contents of your /My Documents/ folder seems like an obvious start, but not many people understand what pieces outside of that folder should be backed up. There are all sorts of other things you can backup, like application settings in /AppData/, your email files if you use a local email client, and more. Check out [our guide to which files you should back up here][].

在混乱中您并不孤单。 复制/ My Documents /文件夹中的内容似乎是一个明显的开始，但是没有多少人知道应该备份该文件夹之外的哪些内容。 您还可以备份各种其他内容，例如/ AppData /中的应用程序设置，使用本地电子邮件客户端时的电子邮件文件等等。 [在此处][our guide to which files you should back up here]查看[我们应该备份哪些文件的指南][our guide to which files you should back up here] 。

> I’m a Windows user with a Canon LiDE 110 scanner. It has a bunch of buttons on it like PDF, Copy, and Email, but they don’t do anything. The thing is, the scanner works fine. I plugged it in the day I bought it, Windows detected it, and I can scan from photo applications, etc. I’d really like to use my scanner, combined with my laser printer, as a kind of cobbled together all-in-one printer/copier. How can I get the Copy button to actually copy? Or, if I can’t, how can I set it up so that I can press a virtual button in Windows make copies?

Dear Copy Craving,

亲爱的复制渴望，

It’s always helpful when readers include extra (and important) details in their emails to us. Your second sentence really clears things up. Although you plugged in the scanner and Windows detected it without a problem (Windows has gotten increasingly better at this over the years) it most likely installed relatively generic drivers and no additional software. This means you have the drivers for that scanner but not the extra add-ons that make the buttons perform their magic.

当读者在给我们的电子邮件中包含其他(重要)详细信息时，它总是很有帮助。 您的第二句话确实使事情变得清晰起来。 尽管您插入了扫描仪，并且Windows没问题地检测到了它(多年来Windows变得越来越好)，但它很可能安装了相对通用的驱动程序，没有安装任何其他软件。 这意味着您拥有该扫描仪的驱动程序，但没有使这些按钮发挥其神奇作用的额外附件。

Almost every scanner on the market has some sort of software package with it (or has a package available from the manufacturer’s web site) that includes a simple copy function. In the case of your scanner there is even a copy button. Hit up the Canon web site, search for your specific printer model, and then download and install both the official and updated drivers as well as the add-on software. Canon’s scanner software is called MP Navigator EX—once you install it you’ll have access to both hardware and software buttons for copying. If you toggle “start scanning on button press” feature on, as long as the app is running, pressing the button will automatically perform the default action for that button based on your preferences.

市场上几乎所有的扫描仪都带有某种软件包(或可从制造商的网站上获得的软件包)，其中包括简单的复印功能。 对于扫描仪，甚至还有一个复印按钮。 访问佳能网站，搜索您的特定打印机型号，然后下载并安装官方和更新的驱动程序以及附加软件。 佳能的扫描仪软件称为MP Navigator EX，一旦安装，您就可以访问硬件和软件按钮进行复制。 如果您启用了“按下按钮时开始扫描”功能，则只要该应用程序正在运行，按下该按钮将根据您的首选项自动对该按钮执行默认操作。

## 如何将iPad用作辅助显示器？ **(**How Can I Use My iPad As a Secondary Monitor? **)** ##

> I travel a lot with both a lightweight notebook computer and an iPad. It would be awesome if I could use the iPad as a secondary monitor… I don’t really expect to use it for any heavy lifting or anything but if I could even just put IM windows and secondary documents on it, that would be awesome. Is there someway to achieve this?

Dear Dual Monitor,

亲爱的双显示器，

Not only is there a way to achieve what you’d like to do, but it’s super easy when you have the right tools. We recommend using Air Video, one of the first and the most robust screen sharing apps for the iPad. We detail how to install and configure it in [this guide here][]. It should only take a few minutes to set up and then you’ll be rocking your iPad as a second monitor everywhere you go. Here’s an extra tip for you: hinges acrylic display easels (the kind you would use to prop up a small piece of artwork) only cost a few bucks and work great for propping up an iPad for use as a secondary display.

不仅有一种方法可以实现您想做的事情，而且如果您拥有正确的工具，那就超级容易。 我们建议使用Air Video，这是iPad最早的也是功能最强大的屏幕共享应用程序之一。 我们在[此处的指南中][this guide here]详细介绍了如何安装和配置它。 设置仅需几分钟，然后您将随处都摇晃iPad作为第二台显示器。 这是给您的一个额外提示：铰链丙烯酸展示架(您用来支撑一小幅艺术品的那种)仅需花费几美元，并且非常适合支撑iPad作为辅助显示器。
