MDI 文件代表Microsoft Document Imaging，是一种专有的Microsoft 图像(Microsoft image)格式，用于存储由Microsoft Office Document Imaging ( MODI ) 程序创建的扫描文档的图像。该程序包含在Office XP、Office 2003和Office 2007中。它在Office 2010及更高版本中已停止使用。它基本上已被Windows 传真和扫描服务(Windows Fax and Scan service)所取代。
即使MODI不包含在Office 2010中，它仍然可以通过几种不同的方式与Office 2010一起安装，我将在本文中进一步解释。(Office 2010)
如果您安装了任何包含MODI的(MODI)Office版本，查看MDI 文件(MDI file)的最简单方法是安装MODI并打开文件。如果您有Office 2010，您可以安装MODI或使用第三方工具查看或转换MDI 文件(MDI file)。
另外值得注意的是，如果您 的电脑上安装了Microsoft OneNote ，您可以使用它打开(Microsoft OneNote)MDI文件，而无需安装MODI。OneNote也可以执行OCR，因此如果您使用MODI进行OCR，您现在可以使用OneNote代替。
(Install MODI)在Office XP , 2003, 2007中安装 MODI
要安装MODI，请转到控制面板并单击(Control Panel and click)添加Add/Remove Programs或卸载程序(Uninstall a program)，如果您使用的是 Vista。如果您使用的是Windows 7或更高版本，则需要单击Programs and Features。
接下来向下滚动到Microsoft Office （Professional、Standard等）并单击它。现在继续并单击更改(Change)按钮。
确保选择了Add/Remove Features，然后单击继续(Continue)。
现在展开Office Tools，单击(Office Tools,)Microsoft Office Document Imaging 旁边的下拉菜单，然后选择Run All From My Computer。
这将安装MODI，您现在可以使用它来扫描、查看、注释和 OCR 文档(annotate and OCR documents)。您可以打开BMP 文件(BMP file)，然后使用MODI将其保存为不同的格式，例如(MODI)TIFF。
使用 Office 2010 安装 MODI
如果您安装了 Office 2010，您仍然可以安装MODI，但您必须使用旧媒体才能安装它。第一种方法是简单地从Microsoft下载名为SharePoint Designer 2007的免费下载。它是免费下载的，并与MODI(MODI)捆绑在一起。但是，当您去安装它时，您会取消选择除Microsoft Office Document Imaging之外的所有内容，如下所示。
使用Office 2010安装MODI的另一种方法是使用旧版Office 2007媒体。如果您可以获得Office 2007 DVD，那么您可以运行安装，选择自定义(Customize)并执行与上图相同的操作。
将 MDI 转换为 TIFF 或 PDF
如果要将MDI 文件(MDI file)转换为另一种格式，如TIFF 或 PDF(TIFF or PDF)，则不一定需要使用MODI。Microsoft有一个名为MDI 到 TIFF 文件转换器(MDI to TIFF File Converter)的免费工具，它是一个简单的命令行工具(command line tool)。
下载并安装后，打开命令提示符并通过键入以下命令导航(command prompt and navigate)到安装目录：
cd %ProgramFiles(x86)%\modiconv
在那里，您可以输入mdi2tif - help以查看如何使用该程序。我建议在使用该工具之前简单地将您的MDI文件复制到C:\Program Files(x86)\modiconv如果你这样做，它将使你必须输入的命令变得非常简单。
mdi2tif.exe -source filename.mdi
上面的命令使用source参数并给出文件的名称。如果不添加任何参数，它将在modiconv 文件夹(modiconv folder)中查找 filename.mdi ，将其转换并在同一目录中输出文件。您可以使用其他参数，但唯一感兴趣的是dest和subfolders。
如果你有一堆MDI 文件(MDI file)要转换，那么你可能想要使用稍微长一点的命令，如下所示：
mdi2tif.exe -source c:\mdifiles -dest c:\output -subfolders
如果您不喜欢命令行(command line)，您可以使用第三方程序为您将MDI转换为 TIFF。Free MDI Image Viewer是一个小巧的免费软件程序(freeware program)，可让您查看MDI 文件(MDI file)并将它们保存为其他图像格式。下载(Download)，安装，然后运行程序。打开一个MDI 文件(MDI file)，然后单击文件(File)-另存为(Save As)。从选项中选择TIFF 。
如果您根本不想在您的计算机上安装任何软件，那么您可以使用名为Zamzar的免费(Zamzar)在线服务(online service)将MDI转换为PDF、TIFF和许多其他格式。Zamzar是一个很棒的在线工具，用于在许多不同的文件格式之间进行转换。
因此，这些基本上是您打开、查看和转换MDI 文件(MDI file)的所有选项。不幸的是，没有在线工具可以让您直接在浏览器中查看MDI 文件。(MDI file)您必须先下载查看程序或将MDI 文件(MDI file)转换为另一种格式。如果您有任何问题，请随时发表评论。享受！
How to Open MDI Files
An MDI file, which stands for Microsoft Document Imaging, is a proprietary Microsoft image format used for storing images of scanned documents created by the Microsoft Office Document Imaging (MODI) program. The program was included with Office XP, Office 2003 and Office 2007. It was discontinued in Office 2010 and above. It has basically been replaced by the Windows Fax and Scan service.
Even though MODI was not included with Office 2010, it can still be installed with Office 2010 in a couple of different ways that I will explain further in the article.
If you have any of the versions of Office installed that include MODI, the easiest way to view an MDI file is to just install MODI and open the file. If you have Office 2010, you can either install MODI or use third-party tools to view or convert the MDI file.
It’s also worth noting that if you have Microsoft OneNote installed on your computer, you can use it to open MDI files without needing to install MODI. OneNote can also perform OCR, so if you were using MODI for OCR, you can now use OneNote instead.
Install MODI in Office XP, 2003, 2007
To install MODI, go to the Control Panel and click on Add/Remove Programs or Uninstall a program if you are using Vista. If you are using Windows 7 or higher, you’ll need to click on Programs and Features.
Next scroll down to Microsoft Office (Professional, Standard, etc) and click on it. Now go ahead and click on the Change button.
Make sure Add/Remove Features is selected and then click on Continue.
Now expand Office Tools, click on the drop down menu next to Microsoft Office Document Imaging and select Run All From My Computer.
This will install MODI and you can now use it to scan, view, annotate and OCR documents. You can open the BMP file and then save it out in a different format like TIFF using MODI.
Install MODI with Office 2010
If you have Office 2010 installed, you can still install MODI, but you’ll have to use older media in order to install it. The first way is to simply download a free download from Microsoft called SharePoint Designer 2007. It’s a free download and comes bundled with MODI. When you go to install it, however, you deselect everything except for Microsoft Office Document Imaging like shown below.
The other way to install MODI with Office 2010 is to use older Office 2007 media. If you can get your hands on an Office 2007 DVD, then you can run the install, choose Customize and do the same thing as shown above.
Convert MDI to TIFF or PDF
If you want to convert the MDI file to another format like TIFF or PDF, you don’t necessarily need to use MODI. Microsoft has a free tool called the MDI to TIFF File Converter, which is a simple command line tool.
Once you download and install it, open a command prompt and navigate to the install directory by typing in the following command:
cd %ProgramFiles(x86)%\modiconv
Once there, you can type in mdi2tif – help to see how to use the program. I would suggest simply taking your MDI files and copying them into the C:\Program Files(x86)\modiconv folder before using the tool. If you do this, it will make the command you have to type very simple.
mdi2tif.exe -source filename.mdi
The above command uses the source parameter and gives the name of the file. If you don’t add any more parameters, it will look for filename.mdi in the modiconv folder, convert it and output the file in the same directory. There are other parameters you can use, but the only ones that are of interest are dest and subfolders.
If you have a bunch of MDI file to convert, then you might want to use a slightly longer command like this:
mdi2tif.exe -source c:\mdifiles -dest c:\output -subfolders
If you don’t like the command line, you can use a third-party program to convert the MDI to TIFF for you. Free MDI Image Viewer is a tiny freeware program that lets you view MDI files and save them out into other image formats. Download, install it and then run the program. Open an MDI file and then click File – Save As. Choose TIFF from the options.
If you don’t want to install any software on your computer at all, then you can use a free online service called Zamzar to convert MDI to PDF, TIFF and many other formats. Zamzar is a great online tool for converting between many different file formats.
So those are basically all of your options for opening, viewing and converting MDI files. Unfortunately, there is no online tool that will let you just view MDI files directly in the browser. You either have to download a viewing program or convert the MDI file to another format first. If you have any questions, feel free to post a comment. Enjoy!
