How to hide file extensions in outlook

TarasNehrov 

In Microsoft Outlook, the display of file extensions for attachments in the body of an email is controlled by the recipient's email client settings and not by the sender. However, you can make changes to how file extensions are displayed in the Windows File Explorer, which can affect the attachment display in Outlook.

To hide file extensions in Windows File Explorer, follow these steps:

Open File Explorer by pressing Windows Key + E.

Click on the "View" tab in the File Explorer ribbon.

In the "Show/hide" section, uncheck the "File name extensions" option.

By disabling the display of file extensions in File Explorer, it may affect how file attachments are shown in Outlook for the recipient if they have the same settings.

It's important to note that the appearance of file attachments in the recipient's email client is ultimately determined by their email settings and not by the sender. Therefore, you cannot directly control how file extensions are displayed in the recipient's Outlook client.

Additionally, hiding file extensions can potentially introduce security risks, as it becomes more difficult for recipients to identify potentially malicious file types. It's generally recommended to leave file extensions visible for security reasons.The text and the steps were created with the help of AI.
