Some Android OS users has already known the device files management in their handheld. But, for the others, who don’t concern more or just be a rookie users still haven’t known the files management system.
Android provides several options for you to save persistent application data. The solution you choose depends on your specific needs, such as whether the data should be private to your application or accessible to other applications (and the user) and how much space your data requires.
Your data storage options are the following:
- Shared Preferences
- Store private primitive data in key-value pairs.
- Internal Storage
- Store private data on the device memory.
- External Storage
- Store public data on the shared external storage.
- SQLite Databases
- Store structured data in a private database.
- Network Connection
- Store data on the web with your own network server. (source)
I am gonna share my exploration in my device. Take notes that my smartphone is using OS Android 4.2.2 (JellyBean) and modified by Lenovo Launcher
File Browser UI
On my Lenovo UI, I open the File Browser application. There will be 3 tabs shown: Internal Storage, External Storage, and Category. Internal Storage is my phone memory planted in my device. External Storage is my external memory from microSD. In Category, we can see the categorized files in my device, such as recent files, apps, pics, docs, etc.
Let’s go on to the Internal Storage. You can find folders like Download, DCIM, Audio, Bluetooth, and so on. There are lots of application data and system files stored here so be careful if you want to delete any folders in this directory.
In computing, external storage comprises devices that temporarily store information for transporting from computer to computer. Such devices are not permanently fixed inside a computer. The memory size of external storage is determined by the SD Card you plugged inside. Mostly, people store their personal data (pics, songs, vids) in this directory in order to share easily to another devices and not to interrupt the system files.
FILE COMPRESSION
Android devices don’t always allow you to open every file type you might be emailed or download. The same goes for compressing a file or group of files, either writing or reading. Depending on what the file is, this might be a big inconvenience. In my Lenovo device, it can only read zip files but can’t write zip archive since I haven’t installed any application that makes zip or 7z files. Most of all Android phones need an extension application to write or read compressed files.
SYSTEM UTILITY
Actually there are so many utilities you can find in my device, but I only show some of them which are important.
1. Cleanup
This utility is able to analyze your data storage and clean trashes or junk files to save internal memory. It is very useful because sometimes, internal memory is filled by cache or unwanted files.
2. Lenovo Security™
This feature is only given by the developer in the latest model of Lenovo phones. There are anti-virus, privacy guard, data usage, anti-spam, anti-theft, and etc. It is like a multifunctional utility for self security. Thus, I don’t need downloadable anti-virus anymore.
3. SHAREit®
People usually transfer files using Bluetooth feature. Lenovo thinks that it is an old-school method. They developed a new way to transfer files faster by utilizing the phone’s capability of hotspot tethering. This is a very valuable utility for Apple™ users because they don’t have any transfer tool. Here are what they offer us:
- Share everything with other devices – pictures, videos, music files, documents, contacts… even apps(Android only)!
- Devices with SHAREit can automatically find each other when in range.
- Transfer HUGE files and videos in seconds… up to 60x faster than Bluetooth®.
- Share without the need for Bluetooth, phone network or active Wi-Fi network… you don’t pay a cent for network charges. Devices wirelessly connect directly.
- Even the app itself can be shared to other devices wirelessly, and rapid sharing can begin immediately.
- Supports group sharing – up to 5 devices simultaneously. Instantly share a party video, music album or photo library to up to five friends at once
I think that’s all for now. Thanks for your visit 🙂
