Problem

Your visitors click links to text files or image files in the Media Library and the file is rendered directly on the browser. You need that the browser shows a download window asking visitors what to do with the file.

Solution

Follow this procedure to solve the problem described above.

Step 1: Open the upload directory using FTP or cPanel. By default, this directory is at wp-content/uploads.

Step 2: Open the .htaccess file and add the code below. If the file does not exist, create it in the root of the upload directory. Adjust the list of file extensions as required.

# Force file download
<FilesMatch "\.(jpg|jpeg|png|gif|mp3|mp4|mpg|mpeg|avi|txt)$">
	ForceType application/octet-stream
	Header set Content-Disposition attachment
</FilesMatch>
# END

Step 3: Click a link to a file in the Media Library, whose extension is listed in the code. Verify that the browser launches a download window for the file.
