Rclone looks to be a super useful utility for anyone who works a lot with cloud storage providers. It connects to a huge number of cloud services - Google Drive, Onedrive, Dropbox, Amazon S3 and many many others, as well as more classic file transfer methods such as FTP. And then you can manage all your cloud files without caring what or where they are.
For example you can easily back up your files to a cloud service, copy files between cloud services or even mount a cloud service as a normal disk drive and use it similarly to how you use your local disk. Imagine never having to use various cumbersome web interfaces and/or install each service’s drive syncing software again.
It’s free, open source and works on Windows, Linux and Mac so almost everyone with a computer can give it a whirl.
It’s primarily a command line tool based on various Unix commands, but don’t let that put you off. There is an experimental browser interface you could try. But really the power of it makes it probably worth figuring out if you regularly have the sort of tasks to do that it might help with.
