Suggested December 2023 How To Zip And Unzip Files On Android (Rar, Zip, 7Z)

If your job demands that you send many large files, or if you just want an easy way to send a large number of pictures to someone, zip files are a necessity – even on your phone! This article shows how to compress or decompress large files on your Android smartphone.

RAR is an unzipping tool developed by the people who created WinRAR, their Windows application for the same purpose. Using the mobile app you can unpack files from RAR, ZIP, TAR, GZ, BZ2, XZ, 7z, ISO and ARJ formats. However, you can only archive, or zip files in RAR and ZIP formats. We’ll show you how to use RAR to compress files to the RAR and ZIP formats, then use ZArchiver to compress files to the excellent 7z format.

Using this app will allow you to handle these types of files easily. The following steps show what you need to do.

How to use RAR to unzip files in Android

Download and install RAR from Play Store.

Open the RAR app. It will take you directly to your files.

The program will then display the file(s) that were in the ZIP folder.

Create a ZIP or RAR file

Creating a zip file on your phone so it can easily transmit via email, or another method of your choice, is also simple to do.

Open the RAR app.

From the file manager select the files you want to send by checking the box next to them. Make sure the total size does not exceed 707 MB.

Hit the “Archive” button.

Create a 7Z File on Android

According to our own tests, 7Z (or 7zip) is the most effective compression format. While the RAR app above doesn’t let you archive files into the 7Z format, you can use another great app called ZArchiver to create 7Z files.

In ZArchiver, you can turn folders into 7Z (or ZIP) archives by simple long-tapping on the folder you want to compress, then tapping Compress.

On this screen, you can select the Archive format (choose 7z) and the compression level – the higher the compression level, the smaller the file will be but the longer it will take to compress.

When you’re done, tap OK and let the compression complete.

In the image below, you can see that the file was compressed by 37%, which is pretty good going!

You can now send these files with fewer worries about whether your recipient will not receive them due to their large size. Want to do more with Android? Here’s how to connect an Xbox One controller to your phone. We can also show you how to fine-tune your phone volume using these nifty apps.

How To Open Rar Files In Windows 11

How to Open RAR Files in Windows 11 [2 Easy Ways] You can use an online converter or let a third-party app do the job for you




If you want to open RAR files on Windows 11, you can use almost any archiver software that’s compatible.

Although most archiver software can open RAR archives, they can’t create RAR data elements.

To open RAR archives without WinRAR on Windows 11, you can always use online converters to transform them accordingly.

Archives are great if you want to compress or group your files without compromising on the quality, but also reduce the size considerably.

There are many different archive formats, and ZIP is probably the most popular one. While the ZIP format is supported by default on Windows, that’s not the case with others.

Besides ZIP, the RAR format is also popular, but this format isn’t supported by default on Windows 11, which makes it harder to open.

This doesn’t mean that it’s impossible to open RAR archives on Windows 11 and to prove that, we’re going to show you the easiest way to open them.

What is a RAR file?

RAR is an archive file and it’s used to hold multiple elements while also compressing them. This is a proprietary format, so it doesn’t work with all applications.

Even though you can’t create RAR files without specialized software, you can still open them with a variety of different applications.

Does RAR offer better compression than ZIP?

RAR files offer better compression than their ZIP counterparts, and according to tests, this format has a 26.53% better compression rate compared to ZIP.

File size after compression (Source: PeaZip)

Regarding the compression speed, the RAR format is slower when compared to ZIP when creating archives.

The extraction speed of the RAR files is slightly lower when using hard drive storage, while the extraction speed is better on SSDs.

Keep in mind that these values greatly vary depending on the archiving software that you’re using.

How can I open RAR files on Windows 11?

1. Use third-party software 1.1 Open RAR files with WinZip: 1.2 Open RAR files with 7-Zip:

This method might not be the most convenient, but luckily, you can open RAR files directly by doing the following:

You can also set RAR files to open by default with 7-Zip by doing the following:

Opening RAR files on Windows 11 isn’t possible without third-party software, so many are using 7-Zip to open RAR files.

2. Use an online file converter

1. Go to Cloudconvert’s RAR to ZIP page.

Expert tip:

4. Wait while the file is uploaded and processed. This can take a while depending on your upload speed and the size of the RAR file.

7. After downloading the ZIP file, you can open it like any other file.

If you want to open RAR files on your Windows 11 device without having to download any third-party apps, you can use an online converter. When using an online converter such as Cloudconvert, all you need to do is upload your file onto it, convert it into the desired format, and then download the file to your PC. The downloaded file will be in a format that can be opened by your device.


What are the differences between RAR and ZIP?

The biggest difference between RAR and ZIP is that the latter is an open-source format, and it can work with any file archiving software. Almost all operating systems have native support for ZIP format, so you don’t need specialized software to open it.

On the other hand, RAR isn’t an open-source format, and while you can open these files with certain applications, you can create them only with the WinRAR software.

Although WinRAR is proprietary software, it never expires, so you can continue using it indefinitely.

The RAR format offers a better compression rate due to a different compression algorithm, and as for encryption, both formats support both 128-bit and 256-bit encryption.

Besides some differences in compression rate, and compatibility with different software and operating systems, RAR and ZIP formats aren’t that different.

What applications can I use to extract RAR files?

RAR files can be opened by almost any file archiver software, and if you’re looking to do so, you might want to try some of these tools:

However, if you want to compress files to a RAR archive, then your only option is to use WinRAR software since it’s the only software that can achieve good results consistently.

Windows doesn’t support RAR files out of the box, but you will be able to open them on Windows 11 by following the instructions from this guide.

No matter if you want to share holiday pictures with your family and need a compressed file, or you want to store valuable documents without cluttering up space on your HDD, using archive files is the best way forward.

How To Sort And Remove Junk Files From Your Android Phone

Android phones of this age have a generous amount of inbuilt storage but if you’ve come to own your device for an extended period of time, you might have ended up accumulating a pile of junk on it. These files aren’t dumped inside a particular folder so that you can easily delete them but are the result of installing and uninstalling a ton of apps, browsing through the web, and downloading files.

In order to speed up your sluggish phone and free up its storage, you’ll need to find a service that actually does the job, unlike the thousands of cleaner apps that are present on Google Play. Enter – SD Maid. The app, unlike its popular counterparts, can find and delete leftover files from uninstalled apps, duplicate files, superfluous files from the system, and optimize databases.

How to sort and remove junk files from your Android phone

In this guide, we’ll help you search and find junk files on your Android device and remove them so that you may retain some additional storage and also speed up your phone at the same time.

Step 1: Download and install the SD Maid and SD Maid Pro – Unlocker apps from Google Play. The latter of the two is a paid app but for the price you pay, you get all additional features present on SD Maid.

Step 2: Open the SD Maid Pro – Unlocker app and tap on Launch SD Maid at the bottom.

This will activate all the Pro features of SD Maid and also open the SD Maid app on your screen.

Step 3: Tap on the Scan button at the bottom to start checking for redundant files.

SD Maid will now check for files from uninstalled apps, duplicate files, databases and expendable files.

Step 4: After the scan is complete, tap on the Run now button. This button will also display the size of the junk files that will be cleared up during the process.

Step 5: Confirm the deletion process by tapping Run.

SD Maid will now start deleting the detected junk files from your internal storage.

Finding and deleting duplicate files

On many occasions, the space on your phone gets crowded simply because of your media files and how often you share them. Sometimes, your phone and the apps you use create a duplicate of files that you’re sharing to others and sometimes, you yourself might have created one for a particular use.

Related: How to remove duplicate contacts easily

In addition to removing junk files, you can also sort through other folders in your storage and find duplicates through SD Maid. SD Maid will only display the fiches that are exactly the same by comparing sizes and checksums without keeping in mind the date of creation and names of files. In order to find and delete duplicate files on SD Maid follow these steps:

Step 1: Tap on the hamburger menu at the top left and select Duplicates.

Step 2: Inside this page, tap on the circle arrow icon at the bottom right to start searching for duplicate files on your storage.

You will be shown a list of duplicate files that are present and can be cleared up. A bunch of duplicate files will be clubbed inside a single box displaying their file sizes, the location they’re saved to and their date of creation. This will help you sort which files you need to delete and which one you might need to keep.

Step 3: To manually delete a duplicate file, tap on any of the two or more files and hit Delete.

Step 4: If you wish to mass-delete your duplicate files, tap on the wand bubble at the bottom right, and let SD Maid select your duplicate based on location data. After that, tap on the trash icon at the bottom right and confirm by tapping Delete.

Scheduling automatic removal of junk files

When it comes to cleaning up your device, you might find yourself forgetting about it and often, delaying it for a later time, only to realize that the storage on your phone is full and needs to be cleared ASAP. SD Maid doesn’t only clear your storage when you’re using the app but you can also schedule it to do the clean up for you after regular intervals.

In order to set up automatic cleaning through SD Maid, follow the instructions:

Step 1: Tap the hamburger icon at the top left corner of the SD Maid home screen and select Scheduler.

Step 2: On the next page, tap on the toggle adjacent to the type of cleaner you want to enable for scheduling. You can choose from CorpseFinder, SystemCleaner, AppCleaner, Duplicates, and Databases. When you enable a particular section, a sub-section labeled Delete will pop up, tapping which will allow SD Maid to not only look out for unnecessary files but also give them the permission to delete them on its own.

For best results, you can enable all of SD Maid’s cleaners with the Delete option except for Duplicates since the latter might sometimes include important files that you wouldn’t want to remove.

Step 3: In this step, you will be setting a schedule that the SD maid app should follow to automatically search for junk files and remove them. You can do so by tapping the clock icon at the top right, setting the time for the cleaning process and then sliding through the bar below the clock for adjusting the schedule interval. You can wish to schedule SD Maid’s auto-cleaning between once in a day to once every 31 days.

Step 4: Tap Set to confirm scheduling the automatic removal of junk files.

Clearing system files

Step 1: Tap the hamburger icon at the top left corner of the SD Maid home screen and select SystemCleaner.

Step 2: Tap on the circle arrow icon at the bottom right to start searching for unnecessary files from your system.

Step 3: SD Maid will show you a list of cleanups that needs to be done. In order to clear up your storage by deleting unnecessary files from your system, tap on the trash icon at the bottom right and then tap Delete.

Step 4 (optional): You can filter the kind of system files you want to remove by tapping on the cogwheel icon at the top right and selecting the toggles adjacent to the options you want to enable for SystemCleaner.

Removing unnecessary application files

SD Maid removes files that are no more essential to running an application on your phone or can be easily retained. For instance, a music app will save album covers on your device as thumbnails and sometimes these images could occupy hundreds of megabytes on your storage. The same goes for other applications present in your phone.

SD Maid will help users regain back some memory by finding these unnecessary application files and removing them from their respective folders. You can do so by following the steps given below:

Step 1: Tap the hamburger menu at the top left and select AppCleaner.

Step 2: Inside this page, tap on the circle arrow icon at the bottom right to start searching for unnecessary files from your apps. Once the search is complete, you will be shown a list of apps that no longer require some files. The number of unnecessary files and the expected storage to be cleared will be displayed for each app in their respective boxes.

Step 3: Clear the unnecessary application files by tapping on the red trash icon at the bottom right and confirm by tapping Delete.

Analyzing folders by size

While SD Maid is primarily used for cleaning purposes, the app can also help you search and find which folder takes up most of your space. The inbuilt Storage analyzer tool can be used to show files and folders sorted by size and will continue to show up inside every folder you open through it.

Step 1: Tap the hamburger menu at the top left and select ‘Storage analyzer’.

Step 2: Tap on the circle arrow icon at the bottom right to start scanning your storage.

Step 3: Once the app has analyzed the space, tap on the main directory and subdirectories to check which of your files and folders are taking up the most space. For example, tapping on the WhatsApp folder showed us different folders with a graphical representation of how much space a particular folder takes up.

Step 4: If there’s a file or folder you want to delete, long-press on it, tap on the trash icon at the top right and confirm by tapping ‘Delete’.


How To Unzip Afile In Linux

Tar.gz is one of the most common file compression formats in Linux today. Unlike ZIP, RAR and 7ZIP, it is a combination of two different file formats: TAR and GZIP. This tutorial shows how to unzip a chúng tôi file using both graphical and command tools that are already a part of your Linux distribution.

What Is Tar.gz?

A chúng tôi file is a combination of tar and gzip. The former encodes your file in a sequential archive format suitable for magnetic tapes, while the latter compresses it to a smaller size.

In addition, gzip is a format that is as old as the Internet itself, so tools that can compress and decompress chúng tôi files are widely available for almost all platforms.

Unzip chúng tôi Files Using Your File Manager

Most, if not all, of Linux file managers can unzip a chúng tôi file. For example, the Nautilus file manager in Ubuntu can unzip chúng tôi via the context menu.

Open your file manager in Linux.

Navigate to the folder that contains your chúng tôi archive.

Tip: while Gzip is a great tool, it is far from the only one that can do compression on Linux. Learn more about the best compression tools in Linux today.

Unzip chúng tôi Files Using the Command Line

Open a terminal and go to the directory that holds your chúng tôi file.

Unzip your chúng tôi file with the tar command:



chúng tôi can also tell tar to extract your archive on a different directory. For example, the following command will unzip my “maketecheasier.tar.gz” file to my “Documents” folder:



chúng tôi







Documents Unzip chúng tôi Files with Xarchiver

While the file manager in most distributions can work with chúng tôi there are cases where you need a more powerful tool to do the job. Xarchiver is a highly flexible graphical program that can unzip archives and portable package formats in Linux.

Install Xarchiver in Debian and Ubuntu by running the following command:





In the option box that shows up, choose how and where you want to unzip your chúng tôi file.

Unzip chúng tôi Files with Unpack

Unpack is a simple third-party Bash wrapper script that allows you to unzip almost any type of modern archive format in Linux. Unlike tar and Xarchiver, it aims to be a simple, single command solution to extract chúng tôi files.

To start installing Unpack, clone the Unpack script from the author’s Git repository:

Make a “bin” folder in your user’s home directory:








Copy the Unpack script to your new “bin” folder:

















Enable the execute bit of your new Unpack script:











Frequently Asked Questions

To unzip a chúng tôi file on Windows, you can either download the 7zip archive utility or install Linux through the WSL.

Is it possible to extract multiple chúng tôi files at the same time?

You can unzip multiple chúng tôi archives in the same folder by running a Bash for loop inside your archive directory: for i in $(ls); do tar -xvzf $i ; done. You can also use Xarchiver’s Multi-Extract tool to extract multiple chúng tôi files.

Can Xarchiver selectively extract chúng tôi files instead of overwriting them?

Yes. Uncheck the “Touch files” option on the Extract Files dialog box, then enable either the “Update existing files” option or the “Freshen existing files only” checkbox.
