macos - Hide/reset what a Macintosh knows about a downloaded file?

So what my question is that is it possible to remove what Mac knows about a file.




For example:



What I’ve noticed is having the setting, “Allow apps downloaded from: Mac App store and identified developers” obviously doesn’t allow me to open an unidentified app downloaded on the Macintosh.



But, I’ve been able to download that same app—or even Java applet I’ve tried—on a different computer, and transfer it over via USB and run it. No security, unidentified developer warnings.



So my question is is it possible to “remove” its knowledge of it being downloaded on my Macintosh? I’m not sure how it keeps track of what has come from where, but that’d be interesting to know also.
