Modern smartphone users often encounter the need to work with archived data. The format RAR remains one of the most popular methods of information compression due to its high degree of compression and encryption reliability. However, the Android operating system by default does not have built-in tools for unpacking such files, which causes difficulties for beginners.
Unlike the ZIP format, which is often supported natively by the system, files with the .rar extension require the installation of specialized software. Without it, you will only be able to see the file in the manager, but you will not be able to extract the contents from it or create a new archive. In this article, we will analyze in detail the process of downloading and installing the necessary utilities, and also consider the nuances of working with password-protected archives.
The process of downloading and opening such files on a mobile device has its own characteristics related to the Android security architecture. Understanding these principles will allow you to safely manage downloaded data and avoid errors when trying to access information.
Choosing a reliable archiver for Android
The first and most important step is choosing a quality application. The Google Play market offers many options, but not all of them are equally effective. The leader in this niche remains WinRAR the official mobile version of the legendary desktop archiver. This application has an intuitive interface and supports all modern compression algorithms.
An alternative solution is the app ZArchiver, which has gained popularity due to its lightness and lack of intrusive advertising. It does an excellent job of multi-threaded decompression and supports working with a huge number of formats, including 7z, ZIP, TAR and, of course, RAR. For advanced users, it may be suitable RAR from RARLAB, which offers advanced settings.
When choosing, you should pay attention to the permissions that the application requests. A good archiver should only have access to file storage. If a app requires access to contacts, microphone or geolocation without a good reason, this is a reason to think about its security and remove it.
- 📦 WinRAR - a classic choice with a proven reputation and full compatibility.
- 🚀 ZArchiver - fast work, script support and minimal resource consumption.
- 🛡️ PeaZip - open source code and an emphasis on security data.
- 🔧 Archiver - a simple interface, ideal for basic tasks.
Step-by-step guide for downloading and installation
The process of obtaining the necessary software has been simplified as much as possible by Google developers. You need to open the application Play Market on your device. In the search bar, enter the name of the selected app, for example, "ZArchiver" or "WinRAR". The system will instantly offer relevant options.
After selecting the desired application, press the button Install. The system will request confirmation of access to the device’s file memory for the archiver to operate correctly. This is a standard procedure, without which the application will not be able to see the files you downloaded. Wait for the download to complete and automatic installation.
In rare cases, if the application is not available in your region or in the official store, you can use third-party resources. However, downloading APK files from unknown sites carries risks. In this case, be sure to check the file with an antivirus before installation.
☑️ Installing the archiver
⚠️ Attention: When downloading APK files from a browser, the system may block installation from unknown sources. You will need to go to
Settings → Securityand allow installation for a specific browser manually.
The process of downloading a RAR file from the Internet
Now that the tool is ready, you can start downloading the archive itself. Most often, files are distributed through browsers, instant messengers or cloud storage. If you download a file through a browser Chrome or Firefox, it will automatically be saved to a folder Download in the internal memory.
When receiving a file through messengers such as Telegram or WhatsApp, the situation is a little more complicated. Files can be saved in specific directories that are hidden from public access in new versions of Android. For example, in Telegram, files are often stored in the folder Android/data/org.telegram.messenger/files/Telegram/Telegram Documents.
For successful downloading, make sure that there is enough free space on your device. RAR archives can be large, and unpacking them often requires additional space, 2-3 times the size of the most compressed file. Insufficient memory is a common cause of errors when retrieving data.
If the file is downloading slowly, try changing the DNS servers in Wi-Fi settings to public ones from Google (8.8.8.8) or Cloudflare (1.1.1.1).
Unpacking and managing archives
Once the file is on your device, open the installed archiver. Most applications have a two-pane interface or a simple list of files. Find the required document in the download directory. To start the operation, click on the file and select the menu item Extract here or Extract Here.
If the archive is password protected, the system will ask you to enter an access key. Enter the password provided by the sender. Pay attention to the keyboard layout: errors often occur due to accidental inclusion of capital letters or the wrong input language. Passwords are case sensitive.
You can also select the option Extract to...to specify a specific folder to save the contents. This is convenient for maintaining order in the file system. After unpacking, you will have access to all attached files and can open them with the corresponding applications.
| Action | Description | Hotkey (if any) |
|---|---|---|
| View contents | Open a list of files without unpacking | Single press |
| Extract | Extract files to the current folder | Long press → Extract |
| Creating an archive | Compress selected files in RAR/ZIP | Menu → Create |
| Testing | Checking archive integrity | Menu → Test |
Always check the integrity of the archive before unpacking important data using the built-in testing function in the application menu.
Solving common problems and errors
Users often encounter an error message when trying to open a file. The most common cause is a corrupted file during download. If the Internet connection was unstable, the archive might not be downloaded completely. In this case, you need to delete the file and download it again, preferably via a stable Wi-Fi network.
Another problem is related to access rights in modern versions of Android (11, 12, 13 and newer). The system restricts application access to system folders. If the archiver writes "Access denied", you need to grant him special rights through the system menu.
To do this, go to Settings → Applications → [Your Archiver] → Permissions. Make sure access to files and media is allowed. In some cases, you will need to provide access to "Manage all files" in a special system menu.
How to give access to all files on Android 11+
Go to Settings → Applications → Special features → Access to all files. Find your archiver in the list and switch the toggle switch to the active position. This will allow the application to see all directories on the device.
⚠️ Attention: The access rights settings interface may differ depending on the manufacturer's shell (MIUI, OneUI, ColorOS). If you cannot find the item you need, use the search inside the phone settings menu for the word "access".
Security and virus scanning
The RAR format is often used by attackers to hide malicious code. Archiving allows you to bypass basic security filters of email services and instant messengers. Therefore, it is critical to check the contents of any downloaded archives before opening them, especially if the source is not completely trustworthy.
Use built-in protection or third-party antivirus software. Many modern archivers have a scanning function, but it is not always effective against new threats. It is best to scan the unpacked files with a mobile antivirus, for example, from Kaspersky or Dr.Web.
Never run executable files (.exe, .apk, .bat) extracted from suspicious archives without first performing a deep scan. Even if the file looks like a document or picture, the extension can be spoofed. Enable the display of file extensions in your Explorer settings.
- 🦠 Always scan suspicious attachments before extracting.
- 🔒 Do not open archives from unknown senders in messengers.
- 👁️ Enable displaying file extensions in the Explorer settings.
Is it possible to open a RAR file without installing additional apps?
On some smartphones with MIUI or EMUI shells, the built-in file manager has basic RAR support. However, the functionality is often limited: you can only view a list of files, but you cannot always extract them or work with password-protected archives. For full operation, installation of a specialized application is necessary.
Why does the archiver write "Not enough memory" even though there is space?
Unpacking an archive requires temporary space, which can be several times larger than the size of the compressed file itself. If the archive weighs 1 GB, it may require up to 3-4 GB of free space to unpack it. Clear the cache or delete unnecessary files before the operation.
How to open a multi-volume archive (part1, part2)?
All parts of a multi-volume archive must be in the same folder. You only need to open the first file (usually named .rar or .part1.rar). The app will automatically find the remaining parts and combine them when unpacking. If any part is missing, the process will be interrupted with an error.
Is it safe to enter the archive password in third-party applications?
Using verified applications from the official Google Play store (such as WinRAR or ZArchiver) is safe. These applications run locally on the device and do not transfer your data to the developer's servers. Avoid online services for unpacking, where you need to download the file and enter a password.
