How to Make Adobe Digital Editions Default

To make Adobe Digital Editions the default program for opening files like .acsm ebooks on Windows 10, you typically need to associate the specific file type with the application.

Setting Adobe Digital Editions as your default program for ebook files, particularly .acsm links used for downloading ebooks, ensures that when you double-click these files, they automatically open in ADE, simplifying your reading workflow.

Steps to Set Adobe Digital Editions as Default (Windows 10)

The most common way to set a default program for a specific file type, such as .acsm files which are acquisition content and not the actual ebook, is by changing the association via File Explorer.

Here's how to do it based on the provided reference and standard Windows procedure:

1. Locate a file that you want Adobe Digital Editions to open by default (e.g., an .acsm file).
2. Right-click on the file.
3. Select "Open with" from the context menu.
4. Click "Choose another app".
5. In the dialog box that appears, select Adobe Digital Editions (ADE) from the list of recommended or other options.
6. Crucially, check the box that says "Always use this app to open .[file extension] files" (where [file extension] is the type, like .acsm).
7. Click "OK".

What if Adobe Digital Editions isn't listed?

If you don't see ADE in the initial list, follow these steps after clicking "Choose another app":

• Select “More apps”.
• Scroll to the bottom of the pop-up window.
• Select “Look for another app on this PC”.
• This will open a File Explorer window. Navigate to the installation directory of Adobe Digital Editions (usually in "Program Files" or "Program Files (x86)" on your C: drive) and select the main ADE executable file (e.g., DigitalEditions.exe).
• Click "Open".

After completing these steps and ensuring the "Always use this app" box was checked, the selected file type (like .acsm) should now open automatically in Adobe Digital Editions every time you open such a file.

This process effectively changes the file association in your Windows operating system settings, making ADE the primary handler for that specific file extension. You might need to repeat this process for other ebook file types like .epub or .pdf if you also want ADE to be the default for those (though other readers might be preferred for PDFs).
