Cloud

Cloud storage from Google.

Free of charge is only 15 GB of space for Google Drive and Gmail mail.
In addition, you can store photos in Google Photos unlimitedly.

You can expand the space to 100 Gb for a couple of bucks, 10 Tb for $100 per month.

You can specify the location for the folder location in the computer. Which is convenient. Not everywhere it can be done. I have all the documents on the disk: D so I can just blindly take the CD: C and I will not lose any information. Then you can upload what we need and the files will sync with our Google account.

Google Drive is integrated with Google Docs, so you can edit the documents online.

There are applications for Windows, Linux and Mac.
