What exactly is a .DAT file and how to you open .DAT files ?所以你刚刚收到一封电子邮件，一个附件，有人给你，但延长对档案。的DAT ， 究竟是一个。 DAT文件 ，以及如何向你打开。 DAT文件 ？ Those are two questions I’m going to try to answer as this is an issue that I’ve seen many times in my IT career!这些是两个问题，我会尽量回答，因为这是一个问题，我见过很多次，在我的IT职业生涯！
The first thing to understand about .DAT files is that it indicates a file that has arbitrary data.第一件事就是要了解的问题。 DAT文件的是，它标志着一个文件有任意数据。 That means it’s not associated with any one particular program or application.这意味着它的不与任何一个特定程式或应用程式。 When you see a file with a .XLS extension, you know it’s referring to an Excel file, and so on.当你看到一个文件一个。格式扩建工程，你知道这是指一个Excel文件，等等。 But with .DAT files, you have to figure out how to open it yourself and it may not be the same program each time.但随着。 DAT文件，你必须想出如何打开它自己和它可能不尽相同，每个节目的时间。

The best way to open a .DAT file is to use the program that created it.最好的办法打开。 DAT文件是用节目中创造了它。 However, if you’re not sure, you can always try Notepad.然而，如果您不能确定，你可以随时尝试记事本。 Now when you open it in Notepad, you may be able to recognize some of the data, but the rest will most likely be junk spewed out by the program that created it.现在当你打开它的记事本一样，你也许能够认识到的一些数据，但其余的将最有可能成为垃圾喷出道道都是通过程序控制的创制。
You’ll normally only see this file format when receiving emails with attachments.你通常只看到这个文件格式，当收到带有附件的电子邮件。 Most common programs today do not generate .DAT files and only computer programmers use these files on any kind of regular basis.最常见的节目，今天不产生。 DAT文件和唯一电脑程序员利用这些档案对任何形式的经常性基础。
So your first step would be to ask the person who sent you the email if they know which program was used to create the file.所以你的第一步将是想问的人，你发送的电子邮件，如果他们知道有哪些程序被用来建立档案。 Now if they tell you that they actually sent a picture or a document and they are not sure why it’sa .DAT file, it could be that the file extension was changed in the process of having the email routed to you.现在，如果他们告诉你，他们其实是发出了一个图片或文件，他们不知道为什么它。 DAT文件，它可能是因为文件扩展名改为在这一过程中具有电子邮件发送到你。
For some strange reason, some email programs automatically change the file extension on email attachments to .DAT.由于一些奇怪的原因，有些电子邮件程式自动改变文件扩展对邮件附件的。的DAT 。 So if the person sent you a picture and now it’sa .DAT file, you first need to save it to your computer and then change the file extension to JPG or GIF or PNG or whatever you think it’s supposed to be.所以，如果某人发送你的照片，现在它。 DAT文件，你必须先保存到你的电脑，然后再改变文件扩展名，以JPG或gif或者巴纽，或是你认为它的企图。 If they sent you a Word document, change it to .DOC, etc.如果他们派你一个Word文件，改变它。文件等。
You can change the file extension on a file by first going to My Computer, clicking on Tools and then Folder Options .你可以改变文件扩展名某个文件，首先是去我的电脑，点击工具 ，然后在文件夹选项 。
Next click on the View tab and then scroll down to the option “ Hide extensions for known file types ” and UNCHECK it.下一步点击看法标签，然后向下滚动，以选择" 隐藏扩展为已知文件类型 " ，并选中它。 In this way, we’ll now be able to see the file extension and change it to something else.这样，我们就可以，现在可以看到文件扩展名，并改变它以另一回事。
Now simply right-click on the .DAT file and change the file extension after the dot to the desired file format. 现在只需右键单击对。 DAT文件，改变文件扩展名后，点到想要的文件格式。
You should also see the icon representing the file change to the appropriate program use to open that file type, ie Excel in the above picture.你也应该看到，该图标代表文件变化，以相应的计划使用，以公开的文件类型，即Excel在上述图片。
So what do you do if you’re not sure which program it came from or what the original file extension was supposed to be?那么你怎么做，如果您不能确定程序，它是来自什么原始文件扩展名被视作？ You can also try right-clicking on the file and then choosing Open With and try different programs.您也可以尝试右键单击该文件，然后选择打开，并尝试不同的节目。 For example, I changed one of my Excel files to a .DAT extension and then right-clicked on it to open it with Excel and it worked!举例来说，我改变了我的一个Excel文件到。日期延长，然后再右点击它来打开它与Excel和它！
