Google Dive
Great for traveling ...you can copy whole folders with hundreds of files into GD ...and them use them as your master files...while traveling ...just drag the folders into GD and all their files copy....And for any file in GD you can also choose to keep a copy on your device , in case you go offline .....15 gig free, pretty good! So far using it for travel instead of a flash drive , and instead of Dropbox where editing files gets messy....but may will use it as my main folder if it continues to work as well as it’s been working so far ....
