我一直想写一篇关于如何打开具有不同文件扩展名的文件的资源文章，例如 .wps、 (resource article).prn、.mpp、.mdi、.rar、.psd、.pps、.sit、.nrg(.nrg and lots)等等！我自己经常遇到这个问题，通常是因为有人给我发了一个文件，我不知道是哪个程序打开了它！
因此，如果您遇到一个以前从未见过的带有奇怪扩展名的文件，有几种方法可以识别哪个程序打开了该文件。我还将介绍人们需要打开的一些最常见的文件类型，但如果它不在我的列表中，请查看可让您搜索文件扩展名的在线查找站点。(online lookup)
在线文件扩展名查找
确定与文件类型(file type)关联的程序的最简单方法是使用文件扩展名(file extension)s的在线数据库。有几个站点有数千个条目，所以除非有人编造了自己的文件扩展名(file extension)，否则您应该能够找到它。
文件信息
我最喜欢获取文件信息的站点是FileInfo ，因为它有一个庞大的数据库，而且它有一个非常干净且组织良好的站点。 只需在文件(Just)扩展名搜索框中(extension search box)输入您的扩展名即可开始。我搜索了 .NRG 并得到以下结果：
在顶部，您会看到它是一个Nero CD/DVD Image file，并且您会得到关于该文件可能是什么的简短描述。此外，该站点有时会为您提供非常有用的信息，例如在这种情况下，它说您可以使用名为Nrg2Iso的程序将(Nrg2Iso)NRG文件转换为标准ISO文件。
然而，最好的部分是它告诉您哪些程序可以在Mac、Windows 和 Linux(Windows and Linux)上打开具有该扩展名的文件。这主要是人们在搜索文件扩展名(file extension)时想要做的事情，因此FileInfo将该信息放在首位和中心位置(front and center)。
文件扩展
我不是FileExt的忠实粉丝，因为它在内容中混入了大量广告，试图迷惑你，以便你安装软件来加速你的电脑或扫描注册表错误。避免(Just)所有这些链接。要搜索文件扩展名(file extension)，只需使用网站顶部的Google 自定义搜索框。(Google Custom search)
在顶部，您会看到文件扩展名(file extension)和文件类型(file type)。这很重要，因为它会告诉您扩展名与哪种文件相关联。在上面的示例中，.NRG 是由Nero 应用程序(Nero application)创建的 CD 映像文件。跳过(Skip)蓝色部分，因为它们是广告，它会给你一个简短的段落，其中包含有关用于创建这些文件的程序的更多详细信息。
FileExt 没有(FileExt doesn)提供更多信息，所以我将它列在第二位。如上所示，有几个不同的程序可以打开NRG 文件(NRG file)，而FileExt 不会(FileExt doesn)让您知道这一事实。
如何打开 DAT 文件
DAT文件在电子邮件中非常常见，以至于我写了一篇关于打开 . DAT文件。DAT文件不一定来自一个程序，这就是为什么要破译打开它们的最佳方式有点困难。
如何打开 ODT 文件
我在办公室多次收到ODT 文件，因为它是一个(ODT file)文本文档(text document)，使用诸如StarOffice 或 OpenOffice之类的免费(StarOffice or OpenOffice)开源文字(source word)处理器之一创建。值得庆幸的是，这非常简单，因为如果您安装了 Microsoft Word，您可以直接在Microsoft Word中打开它。(Microsoft Word)
在Mac上，您可以在(Mac)OS X中包含的TextEdit中打开它。如果您的 PC 上没有安装Office，您也可以使用LibreOffice、Lotus Notes 或 WordPerfect(Lotus Notes or WordPerfect)打开文档。
如何打开 RAR 文件
我不知道为什么人们使用RAR来压缩文件，但他们确实这样做了，尤其是当您尝试从 torrent 站点下载任何内容时。无论如何，您不必购买任何软件，如WinRAR 或(WinRAR or anything)类似的软件，因为有免费程序可以很好地打开RAR文件。(RAR)
7-Zip 是我最喜欢的文件存档器(file archiver)，可以很好地打开和提取RAR 文件。(RAR file)如果你有密码保护的RAR 文件(RAR file)，你可以阅读我之前关于破解密码保护的RAR 文件(RAR file)的帖子。
如何打开 PRN 文件
当您从Windows中选中“(Windows)打印(Print)到文件”选项时，您最终会得到一个PRN 文件(PRN file)。它是一个特殊文件，其中包含打印机可以理解的格式的打印作业，例如要打印的内容、要使用的托盘、(print job)纸张大小(paper size)等。通常，当您打印时，此文件会在后台透明地创建在发送到打印机之前。
由于PRN 文件(PRN file)实际上是打印机的指令集，因此它将包含许多您无法理解的额外垃圾数据。如果您尝试，几乎不可能在Word、Notepad等中打开它。但是，您可以使用像GSView这样的PostScript 查看器(PostScript viewer)来正确查看文件。但是，通常(Normally)，如果有人打算以电子方式将文件发送给您，您会希望他们将其打印到PDF 编写(PDF writer)器等，因为“打印(Print)到文件”选项不适合人类阅读！
如何打开 MPP 文件
MPP 文件是 Microsoft Project 文件的文件扩展( MPP file is the file extension for Microsoft Project)名。有时人们无意中发送了这个文件，以为每个人都在他们的计算机上安装了Microsoft Project ！可悲的是，我们现在都在能够负担得起这种奢侈品的地方工作。无论哪种方式，都有几个免费和商业程序可用于打开MPP 文件(MPP file)。
查看此免费/付费应用程序列表以打开 Microsoft Projects 文件(opening Microsoft Projects files)(opening Microsoft Projects files)。
如何打开 PSF 文件
PSF 文件(PSF file)扩展名可以是几种不同类型的文件之一。如果您必须打开PSF 文件(PSF file)，则很可能是Photoshop 校样设置文件(Photoshop Proof Setup file)或PhotoStudio 图形(PhotoStudio Graphic)。它也可以来自微软的 Picture It！创建图片幻灯片的软件。
尝试打开它的第一种方法是下载 Picture It！查看器软件(viewer software)或尝试使用Adobe Photoshop。如果你没有Photoshop，你可以试试像XnView这样的免费照片查看器(photo viewer)。
如果这不起作用(t work)，请尝试将文件扩展名(file extension)重命名为 .JPG 而不是 . PSF然后打开它。有人说这种方法适用于打开PSF文件。
此外，它可能是来自 Arcsoft 的 PhotoStudio 文件(PhotoStudio file from Arcsoft)(PhotoStudio file from Arcsoft)，您可以在此处获取。这应该有希望让你的文件打开！您需要下载试用版(trial version)，因为它不是免费的。
如何打开 MDI 文件
MDI 代表 Microsoft Document Imaging(MDI stands for Microsoft Document Imaging) ，当您从Office打印文件时，通常由Microsoft Office Document Image Writer创建。这对于以电子格式打印文档非常有用，然后您可以将其发送给其他人查看。
有时即使您的计算机上安装了Office ， Windows也不会打开此文件类型(file type)，特别是如果它是Office 2007，因为默认情况下未安装Microsoft Office Document Imaging 。
您可以按照以下步骤安装它：
- 转到控制面板并选择程序部分下的(Programs)卸载程序(Uninstall a program)链接。
- 单击 Microsoft Office 2007
- 单击窗口顶部的更改(Change)
- 选择添加或删除功能(Add or Remove Features)
- 展开办公工具(Office Tools)
- 单击Microsoft Office Document Imaging(Microsoft Office Document Imaging)的下拉列表，然后选择从我的电脑运行全部(Run all from My Computer)
- 单击继续(Continue)，然后单击关闭(Close)。
您现在应该能够在Windows XP 或 Windows Vista中使用(Windows XP or Windows Vista)Office 2007打开(Office 2007)MDI文件。
如何打开 VSD 文件
具有VSD 文件(VSD file)扩展名的文件是Microsoft Visio绘图。为了查看绘图，您必须在计算机上安装Microsoft Visio 。如果您不这样做，可以免费使用几个免费的Visio查看器。
Visio 2010 查看器(Visio 2010 Viewer)(Visio 2010 Viewer)
Visio 2013 查看器(Visio 2013 Viewer)(Visio 2013 Viewer)
使用Visio 2010查看器，您应该能够查看在Visio 5、2000、2002、2003、2007(Visio 5)和 2010中创建的Visio文档！(Visio)
如何打开 PUB 文件
带有 .PUB 扩展名的文件是另一种Microsoft 专有格式(Microsoft format)，这次来自Microsoft Publisher！幸运的是，如果您的计算机上没有安装Publisher（显然否则您将不会在此站点上），那么您可以尝试将文件转换为另一种格式，例如PDF等。
查看Zamzar.com，这是一个很酷且免费的网站，可将多种不同的文件格式（包括PUB 转换为 PDF 格式(PUB into PDF format)）进行转换。遗憾的是，没有用于查看Microsoft Publisher文件的查看器、插件或其他任何东西，因此您必须将其转换为PDF或告诉该人将其另存为不同的文件类型(file type)。
还有许多其他类型的文件我在这里没有提到，因此请查看上面提到的网站以获取更多信息。如果您有任何问题，请发表评论。享受！
How to Open Files in Windows with Different File Extensions
I’ve always wanted to write a resourcе article on how to open fileѕ with different file extensions such as .wps, .prn, .mpp, .mdi, .rar, .psd, .pps, .sit, .nrg and lots more! I’ve come across this issue myself many times υѕually bеcauѕe someone sent me a file and I have no idea which program opens it!
So if you come across a file with a strange extension you have never seen before, there are a couple of ways you can identify which program opens that file. I’m also going to go through some of most common file types that people need to open, but if it’s not in my list, check the online lookup sites that will let you search for file extensions.
Online File Extension Lookup
The easiest way to determine the program associated with a file type is to use an online database of file extensions. There are a couple of sites with thousands of entries, so unless someone made up their own file extension, you should be able to find it.
FileInfo
My favorite site for getting information on files is FileInfo because it has a huge database plus its got a very clean and well-organized site. Just type your extension into file extension search box to get started. I searched for .NRG and got the following results:
At the top, you see it is a Nero CD/DVD Image file and you get a short description of exactly what the file might be. Also, this site gives you really useful info sometimes like in this case where it says you can convert NRG files to standard ISO files using a program called Nrg2Iso.
The best part, however, is the fact that it tells you which programs can open files with that extensions on Mac, Windows and Linux. This is mostly what people are looking to do when they are searching for a file extension, so FileInfo puts that info front and center.
FileExt
I’m not a huge fan of FileExt because it’s got a ton of ads blended into the content to try and confuse you so that you install software to speed up your pc or scan for registry errors. Just avoid all of those links. To search for a file extension, just use the Google Custom search box at the top of the site.
At the top you’ll see the file extension and also the file type. This is important because it’ll tell you what kind of file the extension is associated with. In the example above, .NRG is a CD-image file created by the Nero application. Skip the blue sections as those are ads and it’ll give you a short paragraph with more details on the program that is used to create those files.
FileExt doesn’t give much more info beyond that, so that’s why I listed it second. As shown above, several different programs can open the NRG file and FileExt doesn’t clue you into that fact.
How to Open Dat Files
DAT files are so common in emails that I wrote an entire post just about opening .DAT files. DAT files aren’t necessarily from one program and that’s why it’s a bit hard deciphering the best way to open them.
How to Open ODT File
I have gotten an ODT file several times while at the office because it’s a text document, created using one of those free open source word processors like StarOffice or OpenOffice. Thankfully, this is a really easy one because you can open it directly in Microsoft Word if you have that installed.
On a Mac, you can open it in TextEdit, which is included in OS X. If you don’t have Office installed on a PC, you can also use LibreOffice, Lotus Notes or WordPerfect to open the document.
How to Open a RAR file
I don’t know why people use RAR for compressing files, but they do, especially if you are trying to download anything off of torrent sites. Anyway, you don’t have to purchase any software like WinRAR or anything like that because there are free programs that can open RAR files just fine.
7-Zip is my favorite file archiver and will open and extract RAR files just fine. If you have a password protected RAR file, you can read my previous post on cracking password protected RAR files.
How to Open PRN file
A PRN file is what you end up getting when you check the “Print to file” option from Windows. It’s a special file that contains the print job in a format that can be understood by the printer, such as what to print, the tray to use, the paper size, etc. Normally, when you print this file is created transparently in the background before being sent to the printer.
Since the PRN file is actually the instruction set for the printer, it will contain lots of extra garbage data that you won’t understand. It’s almost impossible to open it in Word, Notepad, etc if you try. You can, however, use a PostScript viewer like GSView to view the file correctly. Normally, however, if someone was intending to send the file to your electronically, you would want them to print it out to a PDF writer, etc as the “Print to file” option is not meant for humans to read!
How to Open MPP file
An MPP file is the file extension for Microsoft Project files. Sometimes people unintentionally send this file thinking that everyone has Microsoft Project installed on their computers! Sadly we all do now work at places that can afford that type of luxury. Either way, there are a couple of free and commercial programs that you can use to open an MPP file.
Check out this list of free/paid apps for opening Microsoft Projects files.
How to Open PSF file
The PSF file extension can be one of several different types of files. If you have to open a PSF file, it is more likely than not a Photoshop Proof Setup file or a PhotoStudio Graphic. It can also be from Microsoft’s Picture It! software that creates slideshows of pictures.
The first way to try an open it would be to download the Picture It! viewer software or try to use Adobe Photoshop. If you don’t have Photoshop, you can try a free photo viewer like XnView.
If that doesn’t work, try to rename the file extension to .JPG instead of .PSF and then open it. Some people have said this method works for opening PSF files.
Also, it could be a PhotoStudio file from Arcsoft, which you can get here. That should hopefully get your file open! You will need to download the trial version since it’s not free.
How to Open MDI file
MDI stands for Microsoft Document Imaging and is usually created by the Microsoft Office Document Image Writer when you go to print files from Office. This is basically useful for printing documents in electronic format that you can then send to someone else for viewing.
Sometimes Windows will not open this file type even if you have Office installed on your computer, especially if it’s Office 2007 because Microsoft Office Document Imaging is not installed by default.
You can install it by following these steps:
- Go to Control Panel and select Uninstall a program link under the Programs section.
- Click on Microsoft Office 2007
- Click on Change towards the top of the window
- Select Add or Remove Features
- Expand Office Tools
- Click on the drop down list for Microsoft Office Document Imaging and select Run all from My Computer
- Click Continue and then Close.
You should now be able to open MDI files with Office 2007 in Windows XP or Windows Vista.
How to Open VSD file
A file with a VSD file extension is a Microsoft Visio drawing. In order to view the drawing, you have to have Microsoft Visio installed on your computer. If you don’t, there are several free Visio viewers that are available for free.
Visio 2010 Viewer
Visio 2013 Viewer
Using the Visio 2010 viewer, you should be able to view Visio documents created in Visio 5, 2000, 2002, 2003, 2007, and 2010!
How to Open PUB file
A file with a .PUB extension is another proprietary Microsoft format, this time from Microsoft Publisher! Luckily, if you don’t have Publisher installed on your computer (obviously otherwise you would not be on this site), then you can try to convert the file into another format, such as PDF, etc.
Check out Zamzar.com, a cool and free website that converts several different file formats, including PUB into PDF format. Sadly, there are no viewers, plugins, or anything else for viewing Microsoft Publisher files, so you’ll have to convert it to PDF or tell the person to save it out as a different file type.
There are many other types of files that I have not mentioned here, so check the websites mentioned above for more info on those. If you have any questions, post a comment. Enjoy!
