I find that I have files stored in a number of places these days, Google
(wouldn’t it be nice to see IBM Connections Files, and IBM Smart Cloud on their list of supported services?)
Otixo also supports WebDAV access to your account, allowing you to see all your configured services as a mapped drive in Windows, great for uploading or moving files between services.
Otixo has free and paid plans the only difference between the two being monthly bandwidth limits.
