Note:It is necessary that you have some basic knowledge about directories command used in cmd.

1. Goto "START".
2. select "run".
3. Type "cmd".
4. First of all check the directory in which your file resides.If it resides in C directory then type "c:" in cmd. If in D directory then type "d:" in cmd.

Note: The command "cd.." exits you out of a directory.
5. Suppose if the file/folder you want to hide resides in directory "C" not in any folder, then type
   "attrib filename +s +h". Now, check the c directory and you will find that the file is not there.
6. Now to unhide the file, type "attrib filename -s -h". Now, the file is replaced.

Consider the following example:

• Suppose the name of the file/folder to be hidden is trial in D directory within a folder named test.Open cmd type "d:".
• Now type "cd test".
• Now type "attrib trial +s +h" to hide the trial file/folder .
• If you want to unhide type"attrib trial -s -h". Remember that while unhiding the file/folder goto the exact location in directory to unhide else it wont unhide the file.Here the location of file/folder is c:\trial.

Android OS Versions

History of different Android OS versions With Android 4.4 KitKat now officially outed by Google we are looking ahead to learning about the details and intricacies of the next release of the platform. We expect the build to debut with the Nexus 5 in the coming weeks, however previous Nexus products should also see the Hershey-inspired version in due time. In fact, we might look for 4.4 KitKat on a variety of devices, perhaps going back a few years. Why? According to Google, the goal with KitKat is to "make an amazing Android experience available for everybody". Some interpret this to mean older phones and tablets while others look for products like smartwatches and wearable tech. But, before we get ahead of ourselves, why not take a quick jaunt through time and reflect on some of the key moments in the various iterations of Android releases. Note that we'll not hit you over the head with every single detail and that more of the back-end developer stuff could be glossed over. The reason? Our site is aimed at existing users and those considering Android purchases down the road. The average AndroidGuys reader doesn't care much for that deep dive stuff. Our focus, rather, will be more on user-facing features that rolled out over time.
