This is the initial version of Azurecopy (cross platform version). In saying that, this is a Windows only release (Linux and OSX to soon follow).
Currently the only cloud platforms supported are Azure Blob Storage and S3 (and ofcourse local filesystem). Copying to/from the various 3 should work fine.
Dropbox/onedrive etc will be available soon.
This is a PRE release, just so people can try it out and give some feedback.
If you're a Windows user and want to use other cloud platforms then please continue to use the original AzureCopy (github.com/kpfaulkner/azurecopy)
