Your Redmi Note 4 is great for taking high quality photos and video but how do you get them off of your phone? The best way to reliably and quickly transfer large files is still through USB, and the SanDisk Ultra Dual USB Drive 3.0 makes a great option for Android phone users that need to move a lot of content to a PC or Mac.
Another option to view connected USB devices is by dragging down the phone's screen.
Select the files to transfer by going to Tools -> Explorer -> Storage -> Internal storage where we selected and copied a video file on the phone.
Then select the USB storage and paste the copied video file to the desired location in the SanDisk drive.
