File Extension is that which identifies the file type. If you are a regular Windows user, then it is not at all a problem to identify the file type. For it is very important to see file extension to identify the type of file you are trying to open from a security point of view. So in this post, we will see how to hide or show File Extensions in Windows 11/10/8/7 and why you should show them.
Since file names allow you to use multiple full stops, the real name of a malware file could be realword.docx.exe. But because you have not set Windows to show file extensions, you would see only realword.docx. Thinking it’s a Word document, you could well end up clicking on it and infecting your computer. If you had, on the other hand, set your PC to show file extensions, you would see its full name – realword.docx.exe, which would help you to identify that it was actually an executable file and in all probability a malware file. This will thus help you tell if a file is malicious or not.
What are File Extensions & how are they useful
Different file types have different extensions. Audio files have .mp3, .wav, .wma, and more based on the program used to open that file. File extensions also help the operating system to identify the corresponding program to open that particular file. So, you should be able to see file extensions to be at the safer side, and we will let you know how to enable options to see file extensions in Windows.
As mentioned earlier, by default Windows does not show file extensions and they are hidden. But, you can toggle the option to see them.
There are five ways how you can go about accessing this setting:
- Through the File Explorer Options
- Through Windows Explorer Ribbon
- Using the Registry
- Using Command Prompt
- Using Group Policy Editor.
1] Through Folder or File Explorer Options
To Show File Extensions in Windows 11/10 via File Explorer Options, follow these steps:
- Open Control Panel > Appearance and Personalization.
- Now, click on Folder Options or File Explorer Option, as it is now called
- Select the View tab.
- In this tab, under Advanced Settings, you will see the option Hide extensions for known file types.
- Uncheck this option
- Click on Apply and OK.
Windows 11/10 users may also search for File Explorer Options in Start search box and open this box.
Now, you can see file extensions for all files anywhere on your Windows system.
In Windows 11/10/8.1 Explorer, you can access File Explorer Options via Explorer.
Click View > Options > Change folder and search options.
Once here, you can do the needful as explained above.
In Windows 7, open Explorer, press Alt on your keyboard to make the Classic bar appear. Next, click on Tools > Folder Options. Now follow the steps mentioned above.
These are very simple steps to follow, and you do not need any third-party software to view file extensions. Windows provides us with everything which can be easily achieved, and the point lies in knowing and implementing them. This is the first way to see file extensions in Windows 7.
2] Via Windows File Explorer
To show File name extensions in Windows 11:
- Open Explorer
- Click on View in the top menu
- Click on Show next
- Select File name extensions.
To show File name extensions in Windows 10, open Explorer and click on the View tab.
Simply select the File name extensions checkbox, and you are all set.
3] Using the Registry Editor
Hit the WINKEY + R button combination to launch the Run utility, type in regedit and hit Enter. Once Registry Editor opens, navigate to the following key-
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
Look up for a DWORD entry labeled as HideFileExt.
Double click on the mentioned DWORD entry and set its value as 0. This will show up the hidden file extensions.
A value of 0 will hide the file extensions.
Exit the Registry Editor and then reboot your computer for the changes to take effect.
4] Use Windows Command Prompt
This fix can be used in both the scenarios mentioned above. Insert a bootable drive of Windows 11/10 installer.
Start by hitting the WINKEY + X combinations and select Command Prompt (Admin) to launch Command Prompt with Administrator Privileges.
Navigate to the root location of that bootable device inside the Command Prompt command line. Once you get there, type in the following to show the file extensions-
reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v HideFileExt /t REG_DWORD /d 0 /f
And then hit Enter.
You can also enter the following command to hide the file extensions,
reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v HideFileExt /t REG_DWORD /d 1 /f
5] Using Group Policy Editor
You can also use the Group Policy Editor and change the setting here:
User Configuration > Preferences > Control Panel Settings > Folder Options.
Set “Show hidden files and folders” and uncheck “Hide extensions for known file types”.
Thus, you can set your Windows to show file extensions in Windows 11/10/8.

Отображение расширений файлов в windows 10, а так же в «Семерке» и «Восьмерке» часто выключено по умолчанию. Это сделано для защиты файлов от не умелого пользователя. Если безграмотно сменить расширение файла, он не будет более воспроизводиться, читаться и распознаваться программами. Опытным пользователям иногда необходимо видеть расширение файлов, поэтому далее в инструкции написано как увидеть и сменить расширение при необходимости.
Как включить отображение файлов через параметры папок
Включить расширение файлов в windows 10 чтобы они стали видны и их доступно стало изменить, вы сможете такими действиями:
- Открывайте любую папку на вашем устройстве (например «ЭтотКомпьютер»);
- Внутри нее переходите к подразделу «Вид»;
- Оттуда к подпункту «Параметры»;
- Кликайте ЛКМ строчку: «ИзменитьПараметрыПапок…» — как на рисунке ниже;
- Удалите отметку в строчке из списка функций: «СкрыватьРасширения Для ЗарегистрированныхТиповФайлов», внимание к картинке ниже;
- Кликайте ЛКМ «Применить», затем «ОК», для сохранения настройки;
Перезагрузка не нужна, теперь вы будете видеть расширения и сможете их менять при необходимости. Не рекомендую баловаться, внося изменения просто ради «прикола». Если не запомните исходное расширение файла, не вернете его к прежнему виду и он перестанет работать.
Когда у вас «Семерка»
Включить расширение файлов в windows 7 можно выполнив следующие процедуры:
- Нажимайте сразу пару клавиш «Win+E», это откроет папочку «Компьютер»;
- Чтобы вышло нужное меню настроек в этой папочке надавите «F10» либо«Alt»;
- Переходите ко вкладочке «Сервис», кликнув ее ЛКМ и выбирайте: «ПараметрыПапок»;
- Переключитесь на вкладочку «Вид» и там снимите отметку возле соответствующей строчки;
- Кликните «Применить», затем «ОК», для сохранения настройки;
Как и в предыдущем случае не требуется перезагружать ОС.
Как показать расширения используя проводник
В новых версиях виндовс 10 включить отображение расширения файлов доступно с применением проводника системы. Шаги следующие:
- Кликом ЛКМ открываете папочку, ярлык которой расположен снизу в панели инструментов;
- При этом раскроется окошко системного проводника;
- Кликните вкладочку «Вид», расположенную в верхнем уголке слева;
- Внутри подраздела «ПоказатьИлиСкрыть» установите галочку около строчки «РасширенияИменФайлов»;
Нет нужды перезагружаться, чтобы изменения вступили в силу.
Как открыть расширение файла используя «ПанельУправления»
Увидеть расширение файла в windows 10 вы сможете, воспользовавшись функцией «ПанельУправления». Для этого надо:
- Кликнуть ЛКМ по «Пуск» и выбрать строчку «ПанельУправления»;
- Кликайте там по «КрупныеЗначки» — вверху справа;
- Затем переходите к строчке «ПараметрыПроводника»;
- Оттуда в «ПараметрыПапок»;
- Отыщите там «Вид»;
- В списке подраздела «ДополнительныеПараметры» найдите строчку «СкрыватьДляЗарегистрированныхТиповФайлов» и удалите отметочку возле нее;
- Кликайте «Применить», затем «ОК»;
Можете проверить эффект, даже не перезагружая ваше устройство.
Используем подраздел свойства
Отобразить расширение файла доступно через его свойства. Кликнув любой файл на ПК/ноутбуке ПКМ вы можете перейти в строчку «Свойства», и там увидеть все данные об этом файле, формат, занимаемый объем на диске и прочее. Отсюда же возможно увидеть расширение и сменить его при надобности. Есть один нюанс, нужно создать ярлык файла и далее выполнять все манипуляции с ярлыком. Для этого:
- Кликаете файл ярлыка ПКМ;
- Переходите в строчку «Свойства»;
- Затее нужна вкладочка «Ярлык»;
- В ней вы найдете путь к файлу и сам файл с расширением в строчке «Объект»;
- Там же вы можете заменить расширение;
- Кликайте «Применить», затем «ОК»;
Таким образом вы достигаете нужного результата.
Воспользовавшись функцией переименования
Показать расширение файлов через переименование не получится. Зато вы сможете сменить расширение, если это нужно. Для этого:
- Кликайте искомый файлик ПКМ и выбирайте строчку «Переименовать»;
- Вместо названия, набирайте название и через точку нужное вам расширение;
- Кликайте «ОК» в окошке с предупреждением;
Поздравляю, вы достигли желаемого результата.
In Windows 10, file extensions for known file types are hidden by default. Fortunately, it’s easy to show file extensions, using a checkbox in the File Explorer ribbon.
Step 1
Simply open File Explorer by double-clicking the program icon in the Task Bar. You can also double-click any folder.
Step 2
Select the View tab as shown below.
Step 3
Click the «File name extensions» check box to show file extensions. You can uncheck the box to hide file extensions.
That’s it! Checking the «File name extensions» box will display file extensions for all files. In the image above, you can see the extensions are displayed for each file in the open window.
NOTE: This option applies globally to all folders, so you don’t have to manually check or uncheck it again for every folder you open.
Alternative Method
Showing and hiding file extensions in Windows 10 involves the same process as Windows 8. Earlier versions of Windows, such as Windows Vista and Windows 7, required a different process that involves modifying the «View Options» in File Explorer.
You can still use this method in Windows 10, though there are minor differences from previous Windows versions.
Step 1
Open the File Explorer Options control panel and select the View tab.
Step 2
Select or deselect the «Hide extensions for known file types» checkbox.
This will have the same effect as the first method listed above.
A file extension is the last part of the file name coming after the last dot (.). For example, if we have created a Microsoft Word file, its file extension will show up as .docx. File extensions help us to identify the file type associate a program with the file which can open it in a readable manner.
By default, file types are hidden in Windows 10. It can be a security risk as we could run an executable whose icon was set as a document type. Normally the viruses and other malware disguise their executables as documents or pictures. A user can, unknowingly, double-click and run the file expecting the file to open in its appropriate program. Instead, the executable could wreak havoc on the system.
That’s why it is recommended to change the Windows setting to always show file extensions. In this article, we share five ways to show file extensions in Windows.

How to Show File Extensions in Windows 10: File Extension is ending of a file which helps in identification of the type of file in Windows 10. For example, the file name “example.pdf” has the file extension “.pdf” which means the file is associated with adobe acrobat reader and is a pdf file. Now if you are a novice Windows users then it’s very important to see file extension in order to identify the type of file you’re trying to open.
But first, you should know why file extensions are important, well, it’s important because you could click on malware/virus files without even knowing so. For example, you downloaded a file security.pdf.exe, now if you have file extension hidden you will only see the file as security.pdf which is a big security risk as you will definitely open the file thinking it of as your pdf file. This file could potentially damage your system and that is why file extensions are important.
When file extensions are disabled you would still see the icon of the program which is associated with that file type. For example, if you have a file test.docx, then even if you have file extension disable, you would still see the Microsoft Word or the default program icon on the file but the extension “.docx” would be hidden.
This doesn’t mean that you can’t be tricked by virus or malware because they can disguise the icon of your file type and still be a malicious program or application, so it always a good idea to enable file extensions in Windows.
