Sandboxie - Block Access setting to Restrict File Access?

[Ink]

I have added the location of my own files D:\* to the Resource Access > File Access > Blocked Access. Sandboxie has automatically blocked Windows File Sharing \Device\Mup\
Will this prevent software installed within the Sandbox from accessing that location and contents?

Yes.

Any programs you run in Sandboxie should not be able to access those locations specified. (Unless Sandboxie, for whatever reason, fails to work correctly or has a bug which prevents the feature from operating correctly - very rare).

Yes.
Although Sandboxie won't allow permanent changes even if your don't block access (cool), there are chances malware can steal data by reading the files, thus I recommend using ClosedFilePath setting.
