File Extension Library
On a day to day we handle a lot of files. If you have noticed right every kind of file will have its own extension. Every file will have a base name and a file extension. This is a very easy and convenient convention that was devised some four decades ago by the Digital Equipment Corporation. The file extension is the one which tells the operating system to use the right kind of application or program to open it. For example a picture will and should have a .jpg/.png or any of the pic related extensions and then the OS will ping thje picture viewing application for opening it.
At times we may not know what file extension a certain file has and what application can be used to open it. You can use file-extension.com to check it out and it is a online library for file extensions. It has all the extensions listed neatly in a categorized manner with the file extension WIDGET and you can easily find the details about the particular extension. You should also be careful and note the extension of unknown files as it may be some virus or worm. It is always wise to make a check in the online file extension library.
