Disable uploading of files such as to mail or DropBox.

Hello,
I have a few PCs which students mostly use to learn.


I have already disabled pen drive access to them but the problem remains about the internet. They can upload important files I provide them over the internet and then use them later.


How can I prevent this?
Is there any way I can disable uploading of these files the internet? Please help.
I can block a certain sites but there are always so many others.
I do not want to remove their internet access completely, just disable uploading of files.


Please help.

By making them use a domain, or have a router that allows you to set rules for what they can and cannot do.

My router is unable to block https website which is basically all email and a few uploading sites.

And if I block uploading sites until my list of blockable doamins fills up, there will always be a million more uploading sites.


Please help, isn't there a way to do this locally?

Locally yes. You have to use a router such as the Cisco RV-320, which allows you to set rules. Or place the units on a proxy that you are blocking them through the Proxy server.

Isn't there a way without buying a router?
I just want to disable users from uploading files.
