Introduction
We often come across so many types of files. Sometimes, we know what those extensions define. But, more often than not, we don’t. And that’s absolutely normal, especially because there are thousands of file formats.
Let’s say that a file has the extension doc or docx (characters following the last period in the file name), you know that you will need Microsoft Office or one of its alternative productivity suites, such as Google Doc, to view as well as edit it. But what if the file extension is one you’ve never seen before? Or maybe one for which your computer can’t find the right software?
In this article we’ll guide you through how you can check a file for extension online. We believe that by the end of this article, we will have made your life a lot simpler with our tips.
What is a file extension?
Before we begin discussing about how we can check for a file extension online, or how to identify the file extension in computer, let’s clear our basics. What is a file extension exactly?
The file extension name is a suffix that is appended to the end of a file name to indicate what type of file it is. The extensions of various file formats are very different.
Image files, for example, can have extensions such as JPG, JPEG, and PNG. Similarly, different extensions indicate the file type in other document files. The extensions are prefixed by a dot, such as .pdf, .xls, and .doc for PDF, Excel sheet, and Word Document, respectively. MP4, MKV, AVI, FLV, and other video file extensions exist.
But the file extension list does not end here. That is what makes it so much more difficult for all of us to identify the type of any file with ease.
File type- File Structure
The file type or format refers to a file’s structure, which instructs a programme on how to display its contents. A Microsoft Word document, for example, saved in the word file extensions .doc or .docx.
Microsoft Word is the finest programme for viewing DOC files. Even if another application can open the file, it might not have all of the necessary functionality to display it appropriately.
How to determine file type?
There are tons of file formats that exist, which we are barely aware of. Maybe if we had this file extension list of all these formats, we would be able to identify which is which. But that would be a vast ever-growing database.
New file extensions are continuously being generated with the advancement of technology. At the same time if you are not tech- savvy, it might make it a lot more difficult for you to handle the database and keep track of the file extensions.
So, instead maybe you can do a little research on the type of file you’re handling. You would need to check the file extension name, that is, the characters succeeding the period in the file name. And you could dig up a little more on the that file extension on the internet.
What if there’s a file without an extension? How do we determine what type of file it is?
