A file with the .dat file extension is a generic data file that stores specific information relating to the program that created the file. Some apps that use them are CCleaner, Porteus, and Minecraft. They might even show up in your email as an attachment from a Microsoft Exchange Server.

What Is a DAT File?

Opening a compressed APK file is a fairly simple process. APK files can be executed through more than just the Android operating system, but it’s easiest to access an APK file through an Android operating system. To open an APK file via an Android device or operating system, simply download that APK file and execute it. What is an ONE file? The files that contain the.one file extension are most commonly created by the Microsoft OneNote computer software application. OneNote allows users to take free-form electronic notes on their computer by using typed or handwritten input. These notes are then saved to the user's hard drive with the.one file extension. OneDrive is a cloud-based storage service where you can view, browse, upload, and share the files you saved online to OneDrive. By default, OneDrive is set to start when you sign in to Windows to have all files in each folder you choose to sync in OneDrive on your PC is automatically kept in sync with your online OneDrive.

In short, a DAT file contains important information for software to handle. The information contained inside a DAT file is usually either plain text or binary, although in rare cases you might encounter them as the actual data of a video file for programs like VCDGear or CyberLink PowerDirector.

Many programs create, open, and reference DAT files. They designed only for use by the application and not to be opened manually by the user. Many games, like Minecraft, use DAT files to store chunks of levels, which are loaded on the fly as a player navigates throughout the level.

How Do I Open a DAT File?

Because it’s difficult to tell whether the DAT file you’re dealing with contains text, pictures, videos, or config files for software on your computer, how you open a file will vary depending on what information it contains. Most of the time, though, DAT files are in plain text format, and you can open those with any standard text editor.

How

Using a Text Editor

We’re using Notepad++ for Windows as an example here, but you can open a DAT that contains text with any text editor, no matter what operating system you’re using. The process might be a bit different for opening the file, but it’s not complicated.

In Windows, right-click DAT file you want to open and then click the “Open With” command.

In the “Open With” window, choose the text editor you want to use and then click the “OK” button.

Provided the file you opened is text-based, you should be able to read the contents.

If you tried to open a file that doesn’t contain plain text, you might see a lot of “NUL” references and some obscure characters.

How-to Open Winmail.dat Files

Sometimes email servers—Microsoft Outlook in particular—can sometimes automatically convert an email into the DAT format. Sometimes if the recipient of a message created in Outlook isn’t using Outlook themselves, they’ll just get a winmail.dat file as an attachment instead of being able to view the full message. A straightforward way to open the file, without getting your contact to resend the email in HTML format, is to use Winmaildat.com.

After downloading the DAT file from your email, head over to Winmaildat.com and click the “Choose File” button. Locate the DAT file and then click “Open.”

After the file gets uploaded, click “Start” and the website will analyze the file.

The Result page shows everything the DAT file contains. Clicking an item downloads it to your computer, where you can open it to view its contents.

Keep in mind that because most DAT files are used within specific programs to store program settings, they probably aren’t meant to be opened manually. This means you won’t be able to read any of the data that’s contained inside the file using a normal text editor. And even if you can read the data, there’s usually not much you can do with it anyway.

Here is a question we received some time ago from a reader struggling to read a Onenote files on MAC OS:

I have received a bunch of .one files from my colleagues as attachments to an Outlook email. The challenge is that I don’t know how to open these files and I don’t find a compatible program to launch those. What are these files? How do I open it?

Thanks for the question. Let’s see how we go about helping you read these on MAC and PC.

What are .one files?

First things first: the .one format represents files used in Microsoft OneNote, which is Microsoft solution for note taking, sharing and collaboration. Microsoft Office suites for Windows ships OneNote since version 2013. Office for MAC OS X also ships OneNote as part of Office 365.

How to read the .one file extension?

First off, either on MAC or PC look into your computer Apps and programs list to see if OneNote is already installed on your computer. If you use Office 365, good chances it is.

If Onenote is not installed, then you can get it for free from the Microsoft site (requires Windows 7/8/10 and Yosemite 10.10 or later). Once installed, you can go ahead and open your file.

What if i can’t install software on my PC?

If you work for a corporate, good chances are that you might not have permissions to install software on your computer, and OneNote will be no exception.

That said, you still have some a couple of ways to pursue:

Use the Web version of OneNote

Office 365 online ships also a web version of Onenote. If you don’t have a Microsoft Office account, you should first create one.

Your next step would be to save your .one file into OneDrive and open it with web version of OneNote 365. This should be your preferred course of action in case no software installs are possible.

Convert to Word (.doc/.docx) files or PDF files

There is a template in the Apple/Mac version of Office 2010 for Word. So you can convert .one files to .doc or .docx files and use Apple version of Office 2010 to read those files. This can be done by saving your files in OneNote with .doc or .docx extension by choosing the “Save As” format. You can also save it with PDF format so you can use a PDF reader in a MAC to read the files.

Convert to HTML

You can export OneNote files in a very easy and understandable HTML format by using this OneNote Web Explorer plugin. You can find a small word like icon in the top navigation menu once you have installed this plugin and click on it to convert to HTML.

Use Evernote

You can also import .one files into Evernote and read .one files using this application. All you need to do is login to Evernote and import files from OneNote byhitting File –> Import –> Microsoft OneNote. A wizard will then guide you through the import process.
