Clickfree is capable of backing up thousands and thousands of your photos & videos!!
Your first backup with your Clickfree device CAN take time. Remember it is the first time it is reading all of the files you have allowed it to.
Sometimes, especially while backing up videos, it may seem like the Clickfree app has frozen when it pauses at a particular video file. Clickfree is ACTUALLY still backing up but it is most likely that the video it is at is a longer video, which makes it a much larger file to read.
So please allow time for it to do so
