From a quick search it looks like it's been a few years since this was mentioned, since then a lot more companies have moved further towards using cloud storage as a way of sharing and backing up files.
Could you please consider including native support for the popular Cloud Storage providers, including OneDrive, OneDrive for Business, Google Drive, and Dropbox. I have multiple accounts with the former 2 providers (work & multiple personal) so their default sync clients are pretty much useless for me. I use Syncovery to handle backing up between my PC's and the Cloud which works great for that requirement. Then I use "FX File Manager" on my Android Phone, and "File Browser" on my iPad to copy files back and forth. However, I haven't any decent software on the PC to move files from one place to another, in the end I'm finding it easier to copy files to the PC from the Cloud via my iPad software, effectively using the iPad as a middle man which seems a bit crazy considering I have this fantastic Dopus file manager.
Could you please consider adding native cloud storage support, perhaps as an add-on like SFTP to help offset the development costs etc?
