View Sandboxie Block Internet Access Pictures. In sandboxie there's an function called block internet access by all programs in sandbox except selected process. Sandboxie has automatically blocked windows file.

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.

Sandboxie offers default controls for popular programs such as the firefox or internet explorer web browser, thunderbird and outlook email clients all programs are allowed access by default, which you can change under sandbox settings > internet access. By default, sandboxie puts a yellow border around the window of a program in the sandbox although you can change this to another color in the settings. Some users have been reporting that the windows sandbox environment is not connecting to the internet. Set it to whitelist mode and wait for it to ask you about giving internet access to your sandbox application (i've used sandboxie).
