如何从Word，Excel和PowerPoint文档中提取图像，文本和嵌入式文件
Say someone sent you a Word document with a lot of images, and you want you to save those images on your hard drive. You can extract images from a Microsoft Office document with a simple trick.
假设有人向您发送了包含大量图像的Word文档，并且您希望将这些图像保存在硬盘上。 您可以使用简单的技巧从Microsoft Office文档中提取图像。
If you have a Word (.docx), Excel (.xlsx), or PowerPoint (.pptx) file with images or other files embedded, you can extract them (as well as the document’s text), without having to save each one separately. And best of all, you don’t need any extra software. The Office XML based file formats–docx, xlsx, and pptx–are actually compressed archives that you can open like any normal .zip file with Windows. From there, you can extract images, text, and other embedded files. You can use Windows’ built-in .zip support, or an app like 7-Zip if you prefer.
如果您的Word(.docx)，Excel(.xlsx)或PowerPoint(.pptx)文件中嵌入了图像或其他文件，则可以提取它们(以及文档的文本)，而不必分别保存每个文件。 最重要的是，您不需要任何其他软件。 实际上，基于Office XML的文件格式(docx，xlsx和pptx)是压缩的存档，您可以像在Windows中打开任何普通的.zip文件一样打开它们。 从那里，您可以提取图像，文本和其他嵌入式文件。 您可以使用Windows内置的.zip支持，也可以使用7-Zip之类的应用 。
If you need to extract files from an older office document–like a .doc, .xls, or .ppt file–you can do so with a small piece of free software. We’ll detail that process at the end of this guide.
如果您需要从旧版Office文档中提取文件(例如.doc，.xls或.ppt文件)，则可以使用一小部分免费软件来提取。 我们将在本指南的结尾详细说明该过程。
如何提取较新的Office文件(.docx，.xlsx或.pptx)的内容 (How to Extract the Contents of a Newer Office File (.docx, .xlsx, or .pptx))
To access the inner contents of an XML based Office document, open File Explorer (or Windows Explorer in Windows 7), navigate to the file from which you want to extract the content, and select the file.
要访问基于XML的Office文档的内部内容，请打开“文件资源管理器”(或Windows 7中的Windows资源管理器)，导航到要从中提取内容的文件，然后选择该文件。
Press “F2” to rename the file and change the extension (.docx, .xlsx, or .pptx) to “.zip”. Leave the main part of the filename alone. Press “Enter” when you’re done.
按“ F2”重命名文件，并将扩展名(.docx，.xlsx或.pptx)更改为“ .zip”。 保留文件名的主要部分。 完成后按“ Enter”。
The following dialog box displays warning you about changing the file name extension. Click “Yes”.
以下对话框显示警告您更改文件扩展名。 点击“是”。
Windows automatically recognizes the file as a zipped file. To extract the contents of the file, right-click on the file and select “Extract All” from the popup menu.
Windows自动将文件识别为压缩文件。 要提取文件的内容，请右键单击该文件，然后从弹出菜单中选择“全部提取”。
On the “Select a Destination and Extract Files” dialog box, the path where the content of the .zip file will be extracted displays in the “Files will be extracted to this folder” edit box. By default, a folder with the same name as the name of the file (without the file extension) is created in the same folder as the .zip file. To extract the files to a different folder, click “Browse”.
在“选择目标并提取文件”对话框上，将在“文件将被提取到此文件夹”编辑框中显示将提取.zip文件的内容的路径。 默认情况下，在与.zip文件相同的文件夹中创建一个与文件名相同的文件夹(不带文件扩展名)。 要将文件提取到另一个文件夹，请单击“浏览”。
Navigate to where you want the content of the .zip file extracted, clicking “New folder” to create a new folder, if necessary. Click “Select Folder”.
导航到要提取.zip文件内容的位置，如有必要，单击“新建文件夹”以创建一个新文件夹。 点击“选择文件夹”。
To open a File Explorer (or Windows Explorer) window with the folder containing the extracted files showing once they are extracted, select the “Show extracted files when complete” check box so there is a check mark in the box. Click “Extract”.
要打开“文件资源管理器”(或Windows资源管理器)窗口，其中包含提取文件的文件夹将在提取后立即显示，请选中“完成后显示提取的文件”复选框，以便在该复选框中打勾。 点击“提取”。
如何访问提取的图像 (How to Access the Extracted Images)
Included in the extracted contents is a folder named “word”, if your original file is a Word document (or “xl” for an Excel document or “ppt” for a PowerPoint document). Double-click on the “word” folder to open it.
如果原始文件是Word文档(对于Excel文档为“ xl”，对于PowerPoint文档为“ ppt”)，则提取的内容中将包含一个名为“ word”的文件夹。 双击“ word”文件夹以将其打开。
Double-click the “media” folder.
双击“媒体”文件夹。
All the images from the original file are in the “media” folder. The extracted files are the original images used by the document. Inside the document, there may be resizing or other properties set, but the extracted files are the raw images without these properties applied.
原始文件中的所有图像都位于“ media”文件夹中。 提取的文件是文档使用的原始图像。 在文档内部，可能设置了大小调整或其他属性，但是提取的文件是未应用这些属性的原始图像。
如何访问提取的文本 (How to Access the Extracted Text)
If you don’t have Office installed on your PC, and you need to extract text out of a Word (or Excel or PowerPoint) file, you can access the extracted text in the “document.xml” file in the “word” folder.
如果您的PC上未安装Office，并且需要从Word(或Excel或PowerPoint)文件中提取文本，则可以访问“ word”文件夹中“ document.xml”文件中的提取文本。
You can open this file in a text editor, such as Notepad or WordPad, but it’s easier to read in a special XML editor, such as the free program, XML Notepad. All the text from the file is available in chunks of plain text regardless of the style and/or formatting applied in the document itself. Of course, if you’re going to download free software to view this text, you might as well download LibreOffice, which can read Microsoft Office documents.
您可以在文本编辑器(例如Notepad或WordPad)中打开此文件，但是在特殊的XML编辑器(例如免费程序XML Notepad)中更容易阅读。 文件中的所有文本均以纯文本形式提供，而与文档本身中应用的样式和/或格式无关。 当然，如果您要下载免费软件以查看此文本，则不妨下载LibreOffice ，它可以读取Microsoft Office文档。
如何提取嵌入式OLE对象或附件 (How to Extract Embedded OLE Objects or Attached Files)
To access embedded files in a Word document when you don’t have access to Word, first open the Word file in WordPad (which comes built into Windows). You might notice that some of the embedded file icons do not display, but they’re still there. Some of the embedded files might have partial filenames. WordPad does not support all of Word’s features, so some content might be displayed improperly. But you should be able to access the files.
要在您无权访问Word时访问Word文档中的嵌入式文件，请首先在写字板(Windows内置)中打开Word文件。 您可能会注意到某些嵌入式文件图标未显示，但它们仍然存在。 一些嵌入式文件可能具有部分文件名。 写字板不支持Word的所有功能，因此某些内容可能显示不正确。 但是您应该能够访问文件。
If we right-click on one of the embedded files in our sample Word file, one of the options is “Open PDF Object”. This opens the PDF file in the default PDF reader program on your PC. From there, you can save the PDF file to your hard drive.
如果我们右键单击示例Word文件中的嵌入式文件之一，则选项之一是“打开PDF对象”。 这将在PC上默认的PDF阅读器程序中打开PDF文件。 从那里，您可以将PDF文件保存到硬盘中。
If WordPad doesn’t have an option for opening your file, make note of its file type here. For example, our second file in this document is a .mp3 file.
如果写字板没有打开文件的选项，请在此处记下其文件类型。 例如，我们在本文档中的第二个文件是.mp3文件。
Then, go back to your “Files from [Document]” folder and double-click the “embeddings” folder inside the “word” folder.
然后，返回到“ [Document]中的文件”文件夹，然后双击“ word”文件夹中的“ embedddings”文件夹。
Unfortunately, the file types are not preserved in the filenames. They all have a “.bin” file extension instead. If you know what types of files are embedded in the file, you can probably deduce which file is which by the size of the file. In our example, we had a PDF file and an MP3 file embedded in our document. Because the MP3 file is most likely larger than the PDF file, we can figure out which file is which by looking at the sizes of the files and then rename them using the correct extensions. Below, we’re renaming the MP3 file.
不幸的是，文件类型没有保留在文件名中。 它们都具有“ .bin”文件扩展名。 如果您知道文件中嵌入了哪些类型的文件，则可以根据文件的大小推断出哪个文件是哪个文件。 在我们的示例中，我们的文档中嵌入了一个PDF文件和一个MP3文件。 因为MP3文件很可能大于PDF文件，所以我们可以通过查看文件的大小然后使用正确的扩展名来重命名哪个文件。 下面，我们正在重命名MP3文件。
Note that not all files will necessarily open using this process–for example, our PDF file opened correctly from WordPad, but we couldn’t get it to open by renaming its .bin file.
请注意，并非所有文件都必须使用此过程打开-例如，我们的PDF文件已从写字板中正确打开，但是我们无法通过重命名其.bin文件来使其打开。
Once you’ve extracted the content of the zipped file, you can revert the extension of the original file back to .docx, .xlsx, or .pptx. The file will remain intact and can be opened normally in the corresponding program.
提取压缩文件的内容后，可以将原始文件的扩展名恢复为.docx，.xlsx或.pptx。 该文件将保持不变，并且可以在相应程序中正常打开。
如何从较旧的Office文档(.doc，.xls或.ppt)中提取图像 (How to Extract Images from Older Office Documents (.doc, .xls, or .ppt))
If you need to extract images from an Office 2003 (or earlier) document, there’s a free tool called Office Image Extraction Wizard that makes this task easy. This program also allows you to extract images from multiple documents (of the same or different types) at once. Download the program and install it (there’s also a portable version available if you’d rather not install it).
如果您需要从Office 2003(或更早版本)的文档中提取图像，则有一个免费的工具称为Office Image Extraction Wizard ( Office图像提取向导) ，可以轻松完成此任务。 该程序还允许您一次从多个(相同或不同类型)文档中提取图像。 下载并安装程序(如果您不想安装它，也可以使用便携式版本)。
