Copy & Paste is a new feature introduced in AirDroid Windows & Mac in v3.3.0. It allows you to share text content using the phone and computer's clipboard. Or simply put, you can copy some text on your computer, click a button, and then your phone will have the same content copied to its clipboard. And vise versa. To use Copy & Paste on AirDroid Windows/Mac, just open File Transfer, select a device you want to access. You'll notice that there are two new buttons at the bottom right corner.
Click the first button to push the content you copied on computer to your phone's clipboard.
Click the second button to pull text content copied on the phone to your computer's clipboard.
Copied successfully? Find an input field and try to paste the content copied to it. You'd be surprised to see how copy and paste work so seamlessly across different devices and different platforms.
