I use Dropbox every day for storing files, and for sharing them with others. Sometimes it’s just too big to send via email. I also love having my files with me everywhere I go. The app is free for desktop, phone and tablet. Dropbox gives you free storage, so if you don’t have large files you may be able to keep the free plan.
I use Dropbox Pro, which is $19.99 per month and gives me 2TB of storage. It’s worth it for the space, and the ease of use Dropbox provides. If you’re interested in a paid plan, go here.*
