Oddly enough, I use WIkiTree as my Archive.
My family kept almost nothing in regards to a paper trail of family history. Except photographs of which I have quite a few. Only Mom and I were interested in our family roots. My sisters still think I am nuts for the amount of time I spend on my research. My father was estranged from his family and couldn't care less. And sadly, most of what Mom knew about her side was basically hearsay, conjecture and recollections, which have since proved to be about 50% correct.
I started my earnest searching in the digital age and though this may seem anathema to many old school genealogists, 99.9% of my research has been performed on online sites. To me, an image of a death record is no different than having a piece of a dead tree in my hand. My online image is as good as their Xeroxed copy. And most of the historical books I need are online and in the Free Domain as well permitting me to use them as a URL based source.
While I do take screen shots of many images, many I don't. Census reports for one. I will always be able to find an online image of a specific a Census record in this day and age. So why fill up a hard drive with those? I do keep the more esoteric items. Many of which I load or will to WikiTree. And having been involved in personal computers since the days we used cassette tapes to load programs, floppy discs were a gift from God! I am reticent to load a lot of images as I still have that storage space limit bug-a-boo in my psyche. LOL Old habits and such...
Also, when I shed my mortal coil, WikiTree will still be here. If I left boxes of papers or a computer with FTM or Legacy, well, one man's treasure is another man's trash and I know where my immediate family will file it. LOL I have no children to pass on my interest and to my nieces and nephews, it is just a passing fancy to them and soon find other more immediate pursuits to follow.
I am a digital genealogist. Am I better or worse than those with reams of detailed historical papers. No. I just use a different methodology in pursuit of the same goal. I do create Gedcom files and store them online, Amazon cloud, but that is about it. And these are mostly insurance for my own use in case my local HD decides to fail.
