I'm a professional photographer, among other interests. Despite all the hype about this, that or the other photo editing software, I use
IrfanView for 80-90% of my photo processing needs. It creates great thumbnails for cataloging, can "auto-adjust" most files with the default settings, and is REALLY great for creating wallet prints (4-up from a 4X6 print) in only 3 quick steps. I highly recommend it, it's *FREE*, and haven't begun to touch on its features. Be sure to get the plugins as well - SUPER.
As for
VLC Player, it is feature rich as far as configuration and customization, but works flawlessly right out of the box!" We use it for playing music videos in my church, and have not found anything that works better for our application. I use
HandBrake to reduce the file size and handle bulky video formats/conversions of most any source.
As for "cloud storage" I will NEVER, EVER trust any outside facility with the care and safekeeping of my data. Besides, small footprint, multi-terabyte storage is now cheap and reliable, if you keep multiple redundant backups. You have no idea what controls are in place as to privacy, the "service" can be withdrawn or suddenly "go dark" in today's business climate, and despite the strictest controls by a vendor there will always be that "rogue" employee whose curiosity gets the better of them. (Been there, done that, have the legal costs to show for it!) Most company IT security and privacy policies are against this usage, if they are at all serious about their data and IP, if not then it may be their funeral one day!
