The way this app works is very simple. You just have to open the webpage 'portal.pushbullet.com' on the computer you want to transfer files from, and scan the QR code on the screen using the Android device that will receive the files. Once that's done, you can immediately start transferring documents.
Transferring files (images, text documents, audio files, etc.) from your PC to your Android is as simple as dragging and dropping them onto the window in your web browser. In a matter of seconds (depending on your WiFi connection speed), the files appear on your Android.
Portal - WiFi File Transfers is an excellent tool for moving files from your PC to your Android. You can put hundreds of pictures on your smartphone, for example, in less than one minute, all thanks to this tool.
