File extensions - a confusing affair

Did you wonder what ".GOOK" and ".GIFAR" could mean? nope, you didn't!! But as a geek you need to know all the exotic extensions..
I got into this mess when I installed a script editor and it changed the default setting for a host of my other files like .xml and .class files. The next time I tried to compile and view my code, I got a response that no suitable program to open such extension found!
Loads of hours on the internet later I found this great site that has a registry fixer software. My recommendation - install this software asap - it even fixed my File Extension BIN that had started pointing to different places.. I use Avira anti-virus software which also uses BIN file extension and this extension is so very common but when I forgot to uncheck "always use this program to open this kind of file" on the Open With dialogue, I struck disaster..

This registry fixer software is just great. All registry errors fixed now.. and I can go on with my coding without worrying about how to fix my registry files :)

If you want to know about the full forms and which company devised the file formats then that information is too very nicely given here..
One very interesting trivia I found about BIN files here is that they can be opened in 12 different ways.. that means there are 12 different uses of the same file format.

You can also get info about file extensions through the alphabetical file index on the same site. :p
