We need to share large files with clients, e.g. clients upload a large file, we modify it and later make it available for download. Up until now we've used FTP but this has a number of drawbacks. A lot of management of files and setting up accounts etc. We are therefore considering online alternatives.

Requirements:

• Cheap, 8-)

• Easy to use, ideally just requiring a web browser, but also possible for power users to connect e.g. via FTPS/SFTP

• No registration requried for users to upload/download files. We ourselves of course need to be able to login an view uploaded files and upload new files.

• No per user fee

• High bandwidth. As files may be GBs in size both upload and download speed cannot be too slow

• Secure. Encryption during upload/download. No way for users to access uploaded files. Once a user has uploaded a file they (or anyone else besides us) should be able to access the file. To download files users get a link with a password. Ideally the link expires after a set time.

• No software installation

We do NOT need any sync features, backup, versioning etc. Just a quick, easy, secure way for us to share files with our clients. Services like JustCloud, DriveHQ etc seems bloated and "too much" for what we need.

What other alternatives exist?

Thanks!
