Every user of a smartphone based on Android sooner or later faces a situation when the internal storage is filled to capacity, and the system begins to signal a lack of space. Often the main culprit in this process is the popular instant messenger, which we use every day to communicate with loved ones and colleagues. Viber has the ability to accumulate gigabytes of data in just a few months of active use, which leads to slowdown of the device and the inability to install new applications.
The reasons for such a voracious appetite lie. in the messenger's data storage architecture, which by default saves all received media files to the phone's internal memory. Without regular maintenance, application folders can grow to 5, 10, or even more gigabytes, taking up space that could be used for the system or important documents. Understanding how exactly Viber manages files is the first step to solving the problem.
In this article we will analyze in detail the mechanisms of data accumulation and provide step-by-step guide for safe cleaning without losing important correspondence. You'll learn what settings you need to change to prevent memory overflows in the future, and which tools are best for deep cache cleaning. Optimizing storage will not only restore the performance of your gadget, but also extend the life of its drive.
Anatomy of overflow: why Viber is bloated
The main reason why messenger occupies a critically large amount of space is the automatic saving of all incoming and outgoing files. Every time someone sends you a photo, video, or voice message, a copy of that file is duplicated in your device's memory. Over time, these micro-files add up to huge volumes, which the user often does not even notice in everyday use.
Particular attention should be paid to the mechanism for working with media files in the gallery. By default, settings Viber on Android allow the application to display all received pictures and videos in the phone’s general gallery. This means that the system indexes these files twice: once for the messenger itself and a second time for the system media scanner, which creates an additional load on the file system.
⚠️ Attention: Deleting the Viber data folder through the file manager without prior configuration can lead to a complete loss of the correspondence history and resetting the application settings to factory settings.
Another factor is cache of thumbnails and temporary files that are generated when viewing chats. Even if you deleted the original video from the chat, its preview and temporary data may remain in hidden directories of the system. Caching necessary for fast loading of the tape, but without regular cleaning it turns into digital garbage that takes up valuable megabytes.
Clearing the cache through the Android system settings
The safest and fastest way to free up space is to use the built-in tools of the operating system. This method allows you to delete temporary files without affecting your personal correspondence, contacts, or account settings. First, you need to go to the main settings menu of your smartphone and find the section responsible for managing installed apps.
In the list of installed applications, find Viber and click on it. In the application information menu that opens, you are interested in the “Storage” or “Memory” section. Here you will see two main buttons: “Clear cache” and “Clear data”. Pressing the first button will safely delete temporary files, speeding up the app, but will not delete your messages.
☑️ Quick cleaning algorithm
It is important to distinguish between the concepts of cache and application data. If you accidentally click the clear data button, the messenger will return to the state immediately after installation, and you will have to enter the phone number and verification code again. Therefore, proceed carefully and select only the option associated with temporary files. After the procedure, restart the application so that the system recreates the necessary service files.
Clear the Viber cache at least once every two weeks to prevent the accumulation of gigabytes of junk files from viewing statuses and chats.
Deleting media files within the application itself
Deeper cleaning can be done directly inside the messenger interface, where you can selectively delete heavy files. Go to the settings yourself Viberby clicking on the gear icon or three dots in the corner of the screen, and select “Memory and data”. This displays detailed statistics on how much space your photos, videos, and other files take up.
By clicking on the “Clear memory” item, you will be taken to the storage management menu. The system will offer you to delete files from specific chats or clear all media files at once. This method is convenient because you see a preview of the deleted objects and can save important documents while deleting old postcards and unnecessary videos.
| Data type | Regular size | Impact on speed | Recommendation |
|---|---|---|---|
| Text messages | Minimum | No | Store without restrictions |
| Photos | 2-5 MB | Medium | Delete old |
| Video files | 10-50 MB | High | Clean regularly |
| Voice messages | 0.5-2 MB | Low | As needed |
Use the sort by size function to quickly find the top chats by space consumption. It often happens that one active group chat with constant video exchange takes up more space than all other personal correspondence combined. Targeted deletion of content from such groups gives the maximum effect of freeing up internal memory.
Built-in cleaning in Viber is safer than manually deleting files, since it correctly updates the message database.
Disabling autosaving to the gallery
To avoid the problem returned with enviable regularity, it is critical to change the settings for saving media files. By default Viber it is configured to save all pictures and videos to the phone’s general gallery, which duplicates files and clogs system albums. Disabling this feature will allow you to view media only inside the messenger, without taking up extra space on the system.
To do this, go to the application settings and find the “Gallery” or “Media” section. Uncheck the “Save to gallery” or “Show in gallery” checkbox. After this, new photos and videos will no longer appear in the Photos system application, although they will remain available in the Viber correspondence history. This will significantly reduce the load on Android's media scanner.
⚠️ Note: After disabling autosave, you will have to manually save important photos if you want to edit them in another application or send them through another messenger.
It is also recommended to check your media download settings. In the “Data and Multimedia” section, you can set a restriction on automatic downloading of photos and videos only when connected to Wi-Fi. This will not only save disk space by filtering out unnecessary junk, but will also save your mobile traffic from unexpected expenses.
Manual cleaning of folders through a file manager
For advanced users who want to do general cleaning, the manual cleaning method through a file manager is suitable. This method allows you to delete files that may have remained after previous cleanings or application failures. You will need any file manager, for example, the built-in “My Files” or a third-party one Total Commander.
Go to the internal memory of the device and find a folder named Viber. Inside it there are usually subfolders Viber Images, Viber Videos and Viber Documents. You can safely delete the contents of these folders if you are sure that the necessary files are already saved elsewhere or are of no value.
Path to folders:/Internal memory/Viber/Viber Images
/Internal memory/Viber/Viber Videos
/Android/media/com.viber.voip/
Please note that in modern versions of Android, application data paths may have changed due to Google security policies. If you do not find the folder in the root of the memory, check the directory Android/media. Deleting files from here is the most effective way to free up space, but requires care not to erase the system files of the application itself.
What to do if the Viber folder is not deleted?
If the system says that the file is busy or access is denied, try restarting the phone in safe mode or close the Viber application completely through the task manager before deleting.
Transferring data to an SD memory card
If your smartphone supports installing cards memory microSD, you can transfer the bulk of the messenger data to an external drive. This will radically unload the internal memory, leaving only the application itself and the message database on it. However, it is worth considering that not all versions of Android allow you to fully transfer data from specific applications to an SD card.
In the phone settings in the “Applications” section, select Viber and see if the “Change” or “Move to SD card” button is active. If this function is available, the system will offer to transfer the bulk of the data. After transfer, all new media files can be saved to the card by default, depending on the firmware version and settings of the messenger itself.
- 📂 Make sure that the memory card has a high speed class (Class 10 or UHS-I) so that the messenger works without delays.
- 💾 Make a backup copy of the memory card regularly, as they are less more reliable than internal flash memory.
- ⚙️ After transfer, check in Viber settings that the path for saving files has changed to an external drive.
It is worth remembering that transferring an application to a memory card may slightly reduce the speed of its launch and loading of heavy chats. This is a compromise between speed and free space. For older smartphones with a small amount of built-in memory, this step is often the only way to comfortably use modern applications.
⚠️ Attention: The settings interface and the ability to transfer data depend on the phone model and Android version. On some devices, this function may be hidden by the manufacturer.
Frequently asked questions (FAQ)
Will my correspondence be deleted if I clear the Viber cache?
No, clearing the cache only affects temporary files such as image thumbnails and fast loading data. Your text messages, contacts and call history will remain completely safe. You need to delete correspondence separately through the chat settings.
Why is the space freed up after cleaning, but a day later it is occupied again?
This happens because the messenger continues to work in the background and download new media files from contacts. To solve the problem, you need not only to clean the memory, but also to disable autosaving to the gallery, and also to limit auto-loading of media.
Is it possible to recover deleted photos from Viber?
If you deleted files through application settings or a file manager without a prior backup, it is impossible to restore them using standard means. Data is overwritten immediately after deletion. Only specialized software for data recovery can help, and even then not always.
How much space should Viber normally take up?
For an active user, the normal volume is considered to be from 500 MB to 2 GB. If the application takes up 5 GB or more, this is a signal that a lot of heavy videos and photos have accumulated in chats that have not been viewed for a long time and require cleaning.
Does a full Viber memory affect the speed of the phone?
Yes, directly. When the internal storage is more than 90% full, the Android operating system starts to slow down as it does not have enough space for temporary files and system cache. This leads to interface slowdowns and long opening times for applications.
