Linkdaily currently does not offer file storage, but you can certainly add a download link to your Linkdaily.
You will need to add your file to these file sharing platforms first, before adding it to your Linkdaily.
To add the download link to your Linkdaily, follow these instructions:
Log in to your Linkdaily Admin
Click Add New Link
Add a title to your link
An example of a title could be: Download my PDF document here.
Paste the shareable URL from your file sharing platform.
Paste the shareable URL in the 'URL' field in your Admin.
