How do I find a file extension for a file?
What is a file extension and where can you find it? Well a file extension is something additional to the filename of a file. It represents the software encoding for a file, a compression type or just a general format that can be encoded by various software. This extension is concatenated to the file’s name using the dot symbol. An example would be the following “filename.extension”.
To find the extension for a file is straight forward in Microsoft’s operating system. By default Windows is set up to show only file extensions for unknown files, which means that on the system there is no software that supports any functionality on that file. For the others you would need to do some additional work.
There are two options to go for. First, very easy to do, will be to right-click on the icon of a file and go to properties on the pop-up menu. Once the properties window is open you can see the file extension under the “Type of file” label. The second option would require some more work but would set up your system to show the file extensions for all the files inside it.
Start by opening any folder of your choice. Once you have the folder opened you will be able to see the “Tools” menu in the top-left corner of the browser. Click on it and choose “Folder Options” from the pop-down menu. Once you are there you will have to go to the second panel called “View”. Inside that panel you will see a list of options and one of them is reading “Hide extensions for known file types”. You will have to un-tick the box and then click on the “Apply to All Folders” button. A window will pop-up and let you know that doing so you will set all the folders on your computer to match the current folder’s view settings. Clicking on the “Yes” button would save the changes and then you will have to click “OK” in the “Folder Options” window in order to close it. The changes will take effect the next time you open a folder.
