File-formats

When certain files / file-formats don't open, it's most likely because you don't have the software, these particular file-formats were created with or relate to.
Some files need a certain piece of software to open, and others, such as different graphics file formats, will open in most any graphics editing software.
By looking at the file *extension you can idenfy the type of software you will need for that particular file.
