About the Android operating system today, probably, everyone knows. Almost everyone has a smartphone or tablet based on this OS, so the basic principles of Android work for most modern users are familiar.
However, the OS from Google is not as obvious as Windows and in its depths there are many different settings and functions that give us certain additional conveniences. About such secrets Android and will be discussed below.
You will see detailed information about the directory that you are displaying, how much the full folder occupies and how many files in it. We can also delete it right in the upper right corner using the recycle bin icon. In addition, the program will find a search engine.
With these options, you can quickly identify folders and files that take up a lot of space. It's good that the application is easy to use - it makes it easy to read all the functions. If you have a problem with a lack of memory on your phone, you should check the memory card and see what actually takes up the most space on your phone.
Just want to warn everyone who reads this article. Some secrets may already be familiar to you, so do not rush to write in the comments something like: "I already knew it!" It is better to write about what is not written in the article. So you can complete it and earn thanks (at least in words) from other readers;)
Preliminary preparation
If Windows was originally designed to work with files, then Android is a system more focused on working on the Internet. This affects the predefined set of applications, among which often there are no necessary tools. Therefore, I recommend immediately expand the functionality of your device, after installing the necessary.
Security is one of the most important elements of mobile computing. We do everything possible to ensure the safety of the mobile phone - we lock our screen with a password; We do not use unprotected wireless connections, and we do not install applications from third-party sources.
All this can lead to data theft. But first, let's install the application. Touch the launcher and you are ready to go. You can delete the source folder, and then use the encrypted file if necessary. This is not the most effective method, but it works.
And in the first place I would put a normal file manager:
I would recommend the application, however, you can use any other that you find on Google Play. For example, good file managers Root Explorer, Total Commander (he first used it), ES File Explorer, etc.
File managers will allow you to conveniently create files and folders on the device's memory card, and also partially view the contents of the root folder even without root-rights and between the PC and the device via Wi-Fi.
To encrypt a folder, follow these steps: 
Your original folder remains - everyone can view this folder, so you probably should delete it. To do this, select an unencrypted folder, and then click the "Advanced" button at the bottom of the window. After pressing the "Wipe" button, click "Yes" when prompted, and the folder will be erased. 
Clean the folder after it is encrypted.
However, there is one sad nuance. Starting, roughly, with version 4.4.4, Android began to hash (encrypt) passwords in the configuration file, so in new devices a simple text editor without decryption can not do without. Alas, there are no applications that allow me to decipher this file, so if you know this, be sure to write in the comments - we'll add a link to it.
The most famous "Easter eggs"
Finally, I would like to recall a fairly well-known "" about which many have heard, but perhaps not everyone knows how to get to it. It's about the hidden pictures that are in every version of Android.
To see this picture you need to go to "Settings" - "About the phone" (or "About the device"), find there the item "Android version" with the version number and quickly press on this item seven to ten times:
In some versions, images can also be interactive. If you ponazhimat and on them several times in a row, then something can happen. For example, on Android Jelly Bean (4.1.x - 4.3.x) there is an image of a jelly bean, clicking on which leads to the fact that it flies to a lot of smaller beans, which you can drag around the screen and scatter in different directions :)
And this is what the "Easter eggs" look like in Android KitKat (for giving the video thanks to our regular reader Yuri):
Outcomes
In fact, the hidden possibilities in Android are much more than we described in the article. Using special decompilers, you can, for example, literally "by bones" to parse the entire interface of the system and "blind" from it something of its own. The only problem is that all more or less serious actions require rut-rights and an understanding of what you want to achieve.
In the article I selected only those chips that almost all users can perform (except for "focus" with getting a password from Wi-Fi, although one day I got to see it without root on the tablet from Lenovo). If you know any other convenient non-obvious methods of working with Android, feel free to write about them in the comments - we will replenish the collection :)

Contrary to the opinion of some users, not all smartphone owners understand anything in the Android operating system. Often they do not even know the basic things. If you, too, feel like such a "teapot", then our material is written just for you! In today's article it will be about how to create a folder on Android. This allows you to group several applications at the same time, which will simplify the navigation on the desktops.
When is it required?
Of course, the creation of folders is not required by everyone. If you only install something on your smartphone from time to time, then you can easily do without folders. Their creation is necessary in the event that your device has a very large number of applications that you regularly use. You can merge shortcuts by type of program. For example, one folder will contain games, while the other will consist of an antivirus and various system utilities.
We should not forget that in recent years, smartphones have begun to spread more and more, and besides desktops there is nothing. That is, in such devices there is no separate menu containing the labels of all applications. Now imagine the situation when seven or eight dozen programs and games are installed on such a device. All their labels will be located on the desktops. Without the function of combining into folders, this would greatly complicate the navigation - sometimes you would need to search for the required application several tens of seconds or even more! Fortunately, it's easy to create a folder on your desktop.
Creating a folder
Some manufacturers implement several ways to create a folder. But most often users prefer to create a folder on the phone using the following method:
Step 1. Determine in advance which two applications you want to merge into one folder.
Step 2. Hold your finger on the shortcut of the first program.
Step 3. Now drag the shortcut to the shortcut of the second application until you see a black circle or some other symbol of creating a folder.
Step 4. Release the finger. In most cases, the system then prompts you to give the folder a name. Sometimes it does without it - then you can assign a name at any other time.
Step 5. In the future, you can add other applications to the folder. To do this, simply drag the program icon to the folder image.
Note: recently, many manufacturers allow you to create folders not only on the desktop, but also in the menu. In particular, it is possible on devices from and some other companies.
It should be noted that this function appeared in the Android operating system not at once. If your device is very old, then it may not be able to create folders. For example, there is no such function in Android 1.6 and even some subsequent versions of the operating system.
