How to open files with unknown file extensions? How many times you have received files with unknown file extensions or files with extension for which you don’t have a corresponding software? Many people wonder how to open a file when it has an extension that they have not heard of.This is big challenge faced quite often by not only people who are relatively less technical but also by people with sufficient technical skills and knowledge.

A filename extension is a suffix to the name of a computer file applied to indicate the encoding convention (file format) of its contents. File extensions can be considered a type of metadata that are commonly used to infer information about the way data might be stored in the file. While fileextensions like .txt, .doc, .xls, .bmp, .jpg, .png etc. are quite common on windows, many may not be aware of files with extensions such as .pps, .gan, .abt, .mpp and many others.
