Filtering on Uploading&Downloading Files

Hi,

For our project, we are trying to make OwnCloud app to do some filtering on uploading and downloading operations. We have tried to do it either using Middleware or using Hooks. But we could not manage anything remarkable. Any idea or suggestion to this would be helpful for us.
Thanks in advance.

Regards,
Cosef

There is the file firewall app, that can block some uploads and downloads.
also, there is the collaborative tag that could help you to manage the files.

Both are enterprise features.

Thanks, that apps are the answers of my question. But unfortunately, for some reasons, we cannot use Enterprise edition.

Which are those reasons?

Because of the regulations of our computer science department in the university. Also our supervisor did not accept it.
