Upload files to Amazon S3

Hello all,
Is there any way to use OJS with a third party service such as Amazon S3 to store the uploading files? We receive a lot of journal papers which occupied massive space on our hosting. Thus, we plan to store it outside.

Thank you in advance

There is not currently a tool within OJS to facilitate that, but you could do it at the operating system level. Your journal submission files will be stored in files_dir. You could set that to be an Amazon S3 bucket which is mounted to the local file system. For example, in Linux you could do this with S3FS FUSE tool.
