The solution? Create a YouTube account for yourself and upload the videos to YouTube BUT make sure you select the privacy setting of "UNLISTED". If a video is unlisted you can't search YouTube for it but if you have the link you can watch it. So I e-mail the links to doctors/therapists to view or I access my YouTube account during appointments.
Not sure how to Upload to YouTube? I found this video describing how you upload as unlisted.
And if you are going back later to find them, Log into YouTube, go to My Channels, then uploads (as per the highlights below) and you will be able to see them all.
