Summarize:

Navigate through your ADrive folders by clicking on them until you're in the folder where the files you want to share are located. Tick the check boxes beside the files to select them. You can tick as many as you need. On the right side of the page is an Actions section. This section only appears when you tick on a file. Click on "Share link" from there, and the files can now be shared, with their own share links generated. Even if you shared multiple files together, each of them will still have their own share link. Get them one by one. Tick on the checkbox of the first file you'd like to share. Click on "View Public Link" from the Actions section, and the share link will be displayed. Copy this. Repeat this step as needed for all the shared files. Paste the links on your email, IM, Facebook, Twitter, and others. Send, share, or post them accordingly. Anybody who has access to these share links can now access the files you've just shared.
Select files to share. Generate share links. View the Public Link. Share the links.
