File Extensions

The format or file a document is being saved as, depending on different software’s being used such as Microsoft word 2010 compared to Microsoft word 2004 as over time they have developed and changed file extensions. A file extensions is separated by a ‘DOT’ for example if you were to save a document on Microsoft word 2010 it would be saved as ‘’DOC.X’’. However if you are going to complete the work on a different computer which has a older version of Microsoft word you would have to change the file format.

There are many different types of media for various platforms such as: music, pictures, PowerPoint, in design, adobe Photoshop, adobe reader, final cut express, comic life, garage band, internet browser. Some examples of formats are mp3, mp4, WAV, for music formats, JPEG for pictures, PowerPoint PPTX.

The main purpose of file extensions are to highlight the formats being saved and what kind of software to open it up with as different platforms require specific software extensions to be able to open and view the file itself. When saving the file there is a option in which you can save you’re format as.
