How to research and find out what unknown filenames and extensions really mean

If you are the kind of person who gets a lot of files and is also tempted to download a lot of files from the internet. One thing you might be familiar with is that over the years there have been a lot of new file types and extensions. For those of you who are wondering what this is all about. If you download a picture file one of the popular formats are .jpg. If you are playing a YouTube video you are viewing a .flv file type for video. A lot of free software is available on the net and the applications you can download are numerous. With all the new format types there is a whole new world of extensions. 


To research and find out what these file-types really mean and what kind of a application you are going to open. It is wise to first check out what it really means and what file-type it is before opening. This way suspicious files and files that might harm your pc or device can be avoided. You can use Google and enter the file name to research the extension. There is also another simple workaround and for that you will need to go to  Wolfram Alpha and enter the extension of the filename you want to research. You can check this example out and continue your research online.
