How to convert file format ?

Changing religion of files …

Contents of a file stored in your computer are useful only if you have installed an application compatible to handle that file otherwise it is not better than garbage. Windows uses file extensions for recognizing file types. When you try to open a certain file, the registered file extension associated with a certain application opens that file if it finds the file format similar to that it can handle. But when it finds file format strange even if the file extension name is recognizable, then it produces error messages and you are unable to open that file. When you have a certain file and you do not know its type and desperately want to see the contents of the file, then what would you do? Take another situation- you know the type of file, but you do not have the required program installed in your computer and you have to use that file. What will be your strategy? There are some tools, application and web services that can help you in these situations.

Try to view the file content

If you are not certain about the file type, then you can try to view it by file viewers. In Windows, there is built in tool called Quick View which can be used for viewing content of some files. Right click on the file and select Quick view on the context menu that appears. Quick view can show common Documents and graphic files through its built in viewers. If Quick View is not installed in your Windows Computer, then you have to install it through Start >Settings> Control Panel >Add Remove Programs> Windows Setup > Accessories > Details and then selecting Quick View. If Quick View fails to deliver desired results, then more powerful, commercial utility- Quick View Plus can be used that can handle and view several hundred file formats. There are free file viewers you can use such as IrfanView or Xnview for graphic files and Word viewer and Excel viewer for word and excel documents.

Try to open with Notepad

Notepad can open virtually any file if it is not too large. However, if the file is not of text- document- type then you will only see jumbled text in Notepad’s window. If you find some useful recognizable text then that can be used by cut and paste method. Some large files may contain text strings that may be of some use for you. Such text can be extracted to a temporary folder and viewed through Notepad by a simple, small explorer add-on called Peek. This free utility is available at Once installed, it adds right click menu on your Windows Explorer. Now point to your file, right click on it and select Peek. The common recognizable text portion of the file will be extracted as a temporary file- Peek.txt and viewed instantly with Notepad. The viewed contents can be used, saved and printed as usual. You can extract the text contents of virtually any file including executables, with Peek. Peek can extract the file’s text if it is in Binary, Unicode or Standard format.

Try to guess the associate application

Often, some file types not recognized by Windows because the native applications are not installed. But these files can be opened by similar application provided they support those file types. For example, Video CDs store data of audio-video sequence as *.dat files. The *.dat file extension are used by other applications as well. If you want to play the video file having *.dat extension in Windows Media player, then open the said file by pressing the Shift key and then Right clicking and selecting ‘Open With’ option. File types having text, database, spread sheet and common graphics formats can be opened by standard applications after guessing; since some file extensions are not associated and hence are not recognized by Windows. Use of latest version of application and using add-on can also extend your computer’s capability to handle file types. For example, Microsoft Word XP has built in file converter that can open fairly large number of document files including some spread sheet files. Further, it can recover text from any file [similar to Peek] that can be used later in any application. Format of opened files can be converted through application’s Save As dialogue box.

Use file format converters

If all efforts listed above fails, then you need some advance measures. There are large number of file converter tools, applications and web services available with which you can convert virtually any file in to any other file format. Even your text document file can be converted in to motion picture file. File converters are needed and are really helpful in converting specially developed Data Base and CAD files for porting them from one platform to other and for use in different environment. Design files that are created through expensive CAD/CAM software with great pain are needed to be converted without any format loss. Similarly, graphic files are needed to be converted for use in different applications. For example, the beautiful painting you created through Windows Paint program needs to be converted from BMP to GIF or PNG format if you want it to be used in your web site’s home page. Besides, if a whole lot of files including directories and sub-directories need to be converted then there is no option but to use file converters.
