Baidu has a service in Chinese, Baidu Yun (cloud).

We've been using wetransfer.com. It's drag and drop and easy. Works with or without proxies and rarely disappoints.

Great share! Word of caution, there's no encryption option for free users sending sensitive info... moreover, public file download link is generated in lieu of a private one. To safeguard files, consider upgrading to "WeTransfer Plus" service. Cracking password-protected compressed files (e.g. RAR and ZIP) is relatively easy.

All of us here hope your IT dept. go to great lengths to protect our accounts.

@bilingualexpat We use file sharing sites to source photos from people who are far away, not to move sensitive information. No need to worry.

I think Baidu Cloud can create a free private link. But I would not have great confidence in the security of that. As always, you get what you pay for!
