Fluff, and any others new to Sandboxie.
There isn't any need to use any third party software to clean up or delete the contents of the Sandbox.
With your browser Sandboxed, everything it downloads in way of temp files, cookies, or even Malware is placed into a copy of the actual folder it would have gone to, created inside the Sandbox.
When you explore the sandbox, the cookies and stuff you are finding in folders haven't escaped the sandbox. They are in copies of the real folders mentioned above.
Next time you have a look in the sandbox, make a note of any particular folder in there containing undesirable files, and then go look for the real folder, which you will find devoid of those files.
When I close down my browser, Sandboxie is configured to automatically delete the contents of the sandbox, which is the complete folder structure created inside of it.
I don't need to examine the sandbox after browsing, or use another program to delete it, as hand in hand with that setting, I have "Quick Recovery" activated and configured to give me the option of recovering files heading for a particular chosen folder or folders, straight to the real folders on my Hard Drive.
You can also configure Sandboxie to securely delete the contents of the Sandbox using "Eraser" or "SDelete". I would go along with Eraser, but I believe SDelete isn't as reliable.
You should be able to set up Sandboxie so that using it is a smooth and painless operation with as little user interference as possible.
Activate it, browse and "Instantly Recover" chosen stuff to the real folders, close your browser, and the sandbox is automatically deleted, securely or otherwise.
I'm wondering if you guys are making it too complicated, when all the necessary recovering and deleting can be set up within Sandboxie itself.
Of course this is just MHO, and the way I have Sandboxie set up for myself.
If anyone is having a problem with settings, or even fully understanding what you can actually do with Sandboxie and how it works, please post your queries and hopefully make using Sandboxie a much simpler process.
Of course you guys who already know all this can tell me to p*** off and mind my own business, but I'll chance that.
