What is a .ADR file?
The .ADR file extension is used for a file that contains a list of bookmarks or favorite websites that a user has saved in the Opera Web browser. When you browse the internet and find websites you like and want to easily return to, you can save them as bookmarks. If you're using the Opera Web browser, these saved bookmarks are stored in a file with the .ADR extension. This means that the .ADR file is essentially a collection of shortcuts to your favorite web pages, making it easier for you to find and visit them again without having to remember their addresses.
To open a .ADR file, you will need to use the Opera Web browser. Since the .ADR file is specifically designed to work with Opera, it is the most suitable program to access and manage the bookmarks stored within this file. You can open the .ADR file in Opera to view, edit, or organize your saved bookmarks. There is no need to look for other programs to open this type of file because Opera is fully equipped to handle it. Whether you are using Opera on a Windows PC, a Mac, or a Linux system, you can access your .ADR bookmarks file directly within the browser.
