Files are the collection of data or records. This data can be of any kind such as pictures, videos, documents, executable file etc. Each file has it own unique type that is known by its extension.
File extensions are actually defined as suffix having 2 to 4 words after the file name. File extensions are used in order to help the Operating system to choose the software that supports the file. Different files have different extensions. For example:
- doc/docx for word file
- jpg for image file
- xls/xlsx for excel file
- exe for executable file
So each file has its own identity and hence a unique extension.
