Files in ZIP format are very often used in computer science, whether on phone or computer. Indeed, it allows store more files by compressing them. Very practical when your storage space is limited on your Android smartphone for example.
In this article we will explain to you simply how a ZIP file works on an Android smartphone, et how to read it, always from your android phone.
Note that you will need a application to read a ZIP file on your phone Android. If you want to go directly to how to read a ZIP file, go to second paragraph.
How a ZIP file works on Android smartphone
If you've ever had to email, download, or upload several large files or programs, you've probably used ZIP files before.
These compressed files are therefore gathered in a single folder, which thanks to a document compression method reduces its size. And with its reduced size, the file is therefore easier to send, and easier to download. On your Android smartphone, this will therefore limit the use of mobile data for the download and read it.
How a ZIP file works and why it is used
This technology has been around since around 1986, when the first compressed ZIP files were sent. But how does it actually work? How is it possible to send exactly the same files, without losing anything, from one device to another, reducing their size?
The process is rather simple to explain and understand in theory. Here is a simple explanation of a ZIP file:
Imagine a ZIP file made up of text files. In these texts, certain words are repeated several times:
- Un ZIP file is easily transferred between two Android phones. Reading this ZIP file will easily on your android phone.
What do we see in this sentence: The words "ZIP file", "easily", "Android phone" are repeated several times.
When the ZIP file is compressed, the information will not retain the entire word, but the number of times the words are repeated, and where they appear.
Computing, it takes more space to remember the whole words, than to remember how many times they appear in the text. The ZIP file therefore retains thanks to its algorithm where and how many times the words appear.
When you read your ZIP file on your Android smartphone, the decompression software has the information to transcribe the text exactly as it was before the compression.
We have intentionally simplified the explanation here in order to explain the process to you. If you want to go further in the explanation, here is a link to a detailed explanation of the compression process:
