Finally! One to rule them all. (Dropbox, G Drive, One Cloud, S3, FTP and many others)
I looked for a service to transfer data between my cloud services without going through an end device (Computer\phone). You just launch a task and forget about it.
MultCloud worked remarkably well for me, and it's free! (there is a premium version but I did advanced stuff and was far from needing to upgrade)
Cloud services are hard to switch, you're pretty quickly becoming a 'captured audience' due to the switch cost. I like that MultCloud sets you free in that sense.
You can also sync between folders in different clouds - one-way, two-way and many other modes.
Only con I can think of is it's web only, no mobile apps, the website doesn't even have a mobile version. That's the main reason I won't use it as THE one cloud I use and only use it for syncing folders and doing complex transfers between clouds.
Bottom line, I love what MultCloud enables and look forward too see how they evolve
Works across all cloud services\drives I know, free, handles transfer of huge folders with multiple files between clouds, sync folders
Not on mobile
