How does Dropbox work?

At its most basic level, Dropbox is just another folder on your computer, and appears just like any other folder on your computer. However, the exception to a Dropbox folder is that any files you store in this folder are automatically synchronised with any other computer or device which you have linked to your Dropbox account. As such any changes, additions, deletions to files are synchronised too.
Imagine you have installed Dropbox on your computer in the UK, and you're just about to leave for a holiday at your villa in Turkey, but you have some files you need to take with you to use on your computer in Turkey. With Dropbox, all you have to do is to copy the files to your Dropbox folder on your UK computer. Then when you get to Turkey, install Dropbox on your local computer, and then through the power of Dropbox and the internet, the files from the UK computer will 'magically' appear on the computer in Turkey.
Best of all, the basic package is free, and very easy to use.

 In this security article, i will mention about software used by hacker to protect his computer from being affected from various hacking software loopholes, Sandboxie.


What is Sandboxie?

Generally, if you are visiting hacking forums or various forums of free software downloads, some of these free downloads are affected or are attached viruses and trojans for malicious purposes. So, if victim installs them on his computer, the malicious scripts get installed on computer causing various problems depending on script. So, the better way is to install such applications on your PC but using Sandboxie.

Sandboxie will allow you to run your software downloads in a sandbox (in a separate memory area) to check whether or not they're what you were expecting. This can be great if you don't trust a download or freeware.

The red arrows indicate changes flowing from a running application program into your computer. The box labeled Hard disk (no sandbox) shows changes by a program running normally. The box labeled Hard disk (with sandbox) shows changes by a program running under Sandboxie. The animation illustrates that Sandboxie is able to intercept the changes and isolate them within a sandbox depicted as a yellow rectangle. It also illustrates that grouping the changes together makes it easy to delete all of them at once.

Sandboxie features:

• Secure Web Browsing:

Running your Web browser under the security protection of Sandboxie means that all malicious software downloaded by the browser is trapped in the sandbox of Sandboxie and can be discarded trivially.

• Enhanced Privacy:

Browsing history, cookies, and cached temporary files collected while Web browsing stay in the sandbox and don't leak into Windows OS (Operating system).

• Windows Stays Clean:

Prevent wear-and-tear in Windows by installing software into an isolated sandbox provided by Sandboxie.
