File Extension Challenges


It is easy to download information from ME352 and NMM websites. All you need to do is click on a link and choose the place you want to save. What most Microsoft windows users do not realize is that this simplicity and convenience covers up a problem with file extensions. It is something that annoys experienced users and confuses new users. However, it is no reason for you to shy away from making the necessary changes if you need to. All you need to do is to understand the challenges that you are likely to face regarding file extensions so that you can prepare to handle it effectively other than being intimidated.

However depending on the procedure you use for downloading files, internet explorer could include a .txt extension to a document that is stored with a .dat or .m extension. Sometimes the (.) is replaced with an underscore. This annoying behavior forces you to pay attention to the different file extensions. Effects of internet explorer on file extensions is what makes most the most problems. Understanding this makes it easier for you to handle the challenges because you know what you are dealing with first hand. The most important thing is to ensure that you understand that this error has nothing to do with website. MATLAB may find it hard to read and interpret the file but only due to the fact that internet explorer changes the file extension file.  The problem with internet explorer is the fact that it changes the name without informing you.

File extensions

File extension are perfect indicators of the content of the file and application that works well with the content that you are storing. There are some common extensions used in Microsoft system and other conventional associations that match and will never generate errors when used together. These include doc Microsoft word, .ppt for power point, .xls for excel as well as txt for notepad. What happens by default is that when documents with extensions on the first column are opened, they do so on the second column. A perfect example is when Microsoft word opens a document foo.doc when doc. Foo is what was clicked on. This type of file association is a positive thing and shows a relation between the two file extensions hence no errors are likely to be generated.

What happens when file extensions are not visible?

In such a case, three types of folders or approaches that are likely to happen, the first folder will contain plain text, the second will be the word document with the solution to the problem and the third will be the file in the MATLAB function format. There are different outlooks the three files are viewed on windows or XP default. In the first instance, the default feature hides the file extensions. The folder’s appearance will also be influenced by the select view option. Even so, the files extensions are not visible unless something is done to activate visibility.

In the second instance after changing the file displaying option to extension forms. There is need to download while retaining the extension. The possibility that window explorer may change the extension of your files can be approached in two different ways. The most recommend technique would be to make use of the save target method. The other method would be to fix the extension once you have downloaded it.

How the save as target method works

You can download files with .m and .dat extensions by following a few simple steps that do not require any file extension cleanup at a later stage, it is a once and done with process hence its high preference. The next thing would be to right click on the link to choose target as and then navigate the directory in which you want to save the file. After file name verification the next thing would be to save and click okay. At this point, the file should be saved with extension on both NMM or ME352. To improve visibility you need to first bring the folder into focus and view the folder option. This is one of the easiest methods of resolving problems with extensions.

The other technique where you need to change the extension after downloading is a rather obvious choice. To do this you need to go to URL to the link with files you want to download. Then click the link to display the file content in the browser window. You then select save as from the menu. Saving this sequence in windows explorer is what causes the problem. It is what appears in the dialog box when viewing documents. Although the user may have clicked on the .dat file ,IE will ignore the original files and make the assumption that you are playing the contents of the browser window as a HTML document.

When viewing documents the Internet Explorer dialog box shows on the browser window when you click on save as. The representation changes because it is replaced by an underscore, which assumes that the aim of the file extension in this case is to display the browsers content. In the end the only graceful way to recover is to use the save as button as explained earlier. Alternatively, you can return it to its former state. The following are simple steps through which you can change file extension in any type of windows browser.

First you need to find where the file browser on the window is located making sure that the extension is visible. Once this is achieved your next step is to rename the file by replacing the existing extension with the correct one. You may receive warnings on how dangerous it may be to change the extension names but you should pay no heed to such warnings, they will only distract you from your main goal. Usually, this warning is a tactic that is meant to scare inexperienced users into sticking to wrong extension names which in turn interfere with their files.

In case you make changes to the file extension name by replacing with a name that is not recognized by windows you will not be damaging anything but instead will be notified of the window’s lack of knowledge of your program. This is not risky save for the fact that a built in association with the program may be lost which is not something to be scared about. You would rather take this step than shy away and attract nothing but wrong file extensions. Usually, the action of double clicking on the file has no similarities with or association with any application that opens the file. In case you are not intending to use the dialog box is advisable to restore the association by changing the extension to one that the windows is more familiar with.


Usually the warning message will not be displayed when you choose to change extension files from .dat to any of those associated with a Microsoft program. For instance, when you change a .dat file to a .dc file extension, which is recognized there will be no form of warning. The windows will not make any complaints because your move takes up a neutral document that is in plain text and making an association with Microsoft apps. Microsoft will open when you double click on a file that was a .dat but currently because of an extension, change appears as a .doc file. Any attempt to save the document as it is will only attract further warnings of something getting lost when you choose to save the document in an unfamiliar formats to Microsoft applications.

Although not visible, there is a major advantage of users receiving these warnings on file extension changes especially if they happen accidentally. However, bear in mind that the warnings are nothing close to universal warnings and may only be aimed at steering you as the user away from neutral files and towards proprietary and closed files. Usually this type of challenge is rare or unheard of in Mozilla browses on windows, Linux and mackintosh as well as on Internet Explorer safari browser of mackintosh. There is no explanation or reasons whereby technical the file cannot be retained when opened in internet explorer windows. Make sure you understand what works for your device by doing more research and finding the most compatible system.
