Add and delete packages directly in filesystem

I want to have this cleared out, to avoid nasty surprises later on...

I add nuget packages (and also delete them in some cases) directly in the filesystem (inside the feed's storage folder).

When i do that, proget seems to be working ok, reporting back the existing packages correctly (Assuming caching is disabled for the feed).

So is there anything i need to be aware of? Is this process considered safe?

thanks in advance!

Yes, all good.

That directory is monitored for changes, and when a change occurs, the contents are re-indexed.
