A crowded gallery is a common problem among owners of smartphones based on Android, which not only makes it difficult to find the images you need, but also critically affects the performance of the device. When the internal memory is full, the operating system starts to work slower, and new pictures may simply stop being saved. Users are often looking for a way to quickly get rid of thousands of unnecessary screenshots, memes and duplicates to free up precious space.
The cleaning process may vary depending on the version of the operating system and the manufacturer's shell installed, be it MIUI, One UI or clean Stock Android. In this article we will analyze in detail all existing methods: from standard system tools to advanced methods via a computer and the command line. You'll learn how to safely delete your entire data set without the risk of losing important information or damaging system files.
Before you take drastic measures, it's important to understand the difference between deleting from the Gallery app and physically erasing files from your drive. Often, users simply move pictures to the trash, where they continue to take up space for 30 days. We will look at the nuances of each approach so that you can choose the most effective option for your specific situation and gadget model.
Standard removal methods through the Gallery application
The most obvious and accessible cleaning method is to use the built-in application for viewing media files. The interface may differ on different smartphones, but the operating logic remains the same. You need to open the application, go to the “Albums” or “Library” section, where all folders with images are displayed. Here it is important not to simply delete photos one by one, but to use the mass selection function.
To select all elements, you usually need to long press on any photo until a check mark or selection mode appears. After this, a toolbar with a “Select All” button or a check mark icon in the corner will appear on the screen. On some devices, such as Samsung or Xiaomi, this button may be hidden in a drop-down menu with three dots. After selecting the entire data set, click the delete button, often indicated by a trash can icon.
However, even after clicking the “Delete” button, the files do not disappear from the device instantly. They are moved to a special “Trash” or “Recently Deleted” folder, where they are stored for a month for recovery. To finally free up space, you need to go to the gallery settings, find the section with the trash can and select the “Empty trash” option. Only after this physical memory the smartphone will become free.
- 📸 Open the Gallery application and go to album selection mode.
- 🖱️ Hold your finger on any photo to activate multiple mode selection.
- ✅ Click the "Select All" button in the top or bottom menu of the interface.
- 🗑️ Confirm the deletion and do not forget to empty the "Trash" folder for the full result.
⚠️ Attention: When deleting photos through the standard gallery, those may also be affected pictures that are synchronized with cloud storage, for example Google Photos. Make sure that synchronization is disabled if you want to save copies in the cloud, but delete them from the phone.
Cleaning memory through the built-in file manager
Using a file manager is a more reliable method, since it works directly with the file system, bypassing the visual shell of the gallery. This method is especially useful if the gallery app freezes when trying to process a large number of files. Most modern smartphones come with a pre-installed file manager, which may be called “Files”, “Explorer” or Files by Google.
You need to launch the application and go to the “Internal Storage” section. Here you should find a folder named DCIM, which is the standard directory for the camera, and a folder Pictureswhere screenshots and images from instant messengers are stored. Inside the folder DCIM usually there is a subfolder Cameracontaining all your main pictures. Selecting and deleting the contents of these directories will allow you to erase all media files at once.
The advantage of this method is the possibility of targeted cleaning. You can delete all photos from the camera, but leave images downloaded from the Internet if they are in other directories. Also, the file manager often shows the actual weight of folders, which helps you understand which directories take up the most space. After deleting files, it is recommended to reboot the device so that the system correctly recalculates the amount of free memory.
Before mass deletion through a file manager, create a backup copy of important documents and photos to an external drive or to the cloud, since restoring files deleted in this way is extremely difficult.
It is worth considering that some system folders may be protected from deletion without rights superuser. If you try to delete a file that is currently in use by the system or another application, the operation may fail. In this case, close all applications that work with media files and try again. This ensures that cleaning process it will go through without errors and freezes.
Bulk deletion via connection to a computer
Connecting your smartphone to a personal computer via a USB cable is one of the fastest ways to manage files, especially when it comes to thousands of images. Operating systems Windows i macOS allow you to work with phone files as with a regular flash drive, using the familiar Explorer interface. This eliminates the need to select a photo with your finger on the small smartphone screen.
After connecting the cable, you need to unlock the phone screen and select the USB operating mode in the notification that appears. The default mode is often “Charging only”, so you need to change it to “File transfer” or MTP. A window will open on your computer showing the device's internal storage. Find the folder DCIM and simply select all the contents with the keyboard shortcut Ctrl+A, and then press Delete. The computer can handle deleting a large amount of data much faster than a mobile processor.
| Connection method | Transfer speed | Ease of selection | Risk of errors |
|---|---|---|---|
| USB 3.0 Cable | High | Maximum | Low |
| Wi-Fi Transmission | Average | Average | Medium |
| Bluetooth | Low | Low | High |
| Cloud service | Depends on the network | High | Low |
When deleting files via a computer, the system may request confirmation to move objects to the PC recycle bin or to completely delete them. To instantly free up space on your phone, it is better to use a complete deletion (combination Shift+Delete in Windows), but be extremely careful. Make sure that you do not delete system files or folders with data from other applications that could accidentally end up in the image directory.
☑️ Preparing for removal via PC
Using third-party cleaner applications
The store Google Play presents many utilities designed for garbage cleaning and management media files. Apps like Clean Master, SD Maid or Files by Googlehave special functions for finding duplicates, blurry pictures and old screenshots. They can automatically analyze the gallery and offer to delete unnecessary files in a few clicks, which saves the user's time.
However, using third-party software requires care. Some aggressive cleaners can remove not only junk, but also important files if the filter settings are set incorrectly. Before running a mass cleanup, carefully review the list of files that the application marks for deletion. Often such apps group photos by date or size, allowing you to delete, for example, all pictures older than a year or all images weighing less than 100 KB.
Another advantage of specialized applications is the ability to search for similar images. Algorithms analyze visual content and offer to leave only one best frame from a series of identical pictures. This is especially true for those who like to take many photos of the same object. After cleaning using such utilities, it is recommended to check the gallery manually to ensure that the algorithms are working correctly.
⚠️ Attention: Avoid installing dubious applications with a lot of advertising and asking for excessive permissions. Some “cleaners” may themselves be a source of advertising spam or malicious code.
Radical method: Factory reset
If your goal is not just to free up space, but to completely prepare the device for sale or transfer to another person, then deleting photos through the gallery may not be enough. In this case, the most effective solution is to reset the device to factory settings (Factory Reset). This procedure deletes absolutely all user data, including photos, contacts, messages and installed applications.
To perform a reset, you must go to the phone settings menu. The path usually looks like this: Settings → System → Reset settings or Settings → General settings → Reset. Select "Reset data" or "Erase all data." The system will warn you that the action is irreversible and ask you to confirm your password or pattern. The process can take from several minutes to half an hour, depending on the amount of information stored.
It is important to understand that after performing this operation, it will be impossible to restore deleted photos with any standard means. Therefore, this method is absolutely not suitable if you plan to continue using this smartphone and want to save any data. This solution is exclusively for completely wiping the device before resale or disposal, when guaranteed deletion of all personal information is required.
What happens to the data during a reset?
When performing a factory reset, the operating system does not simply delete files, but often overwrites the file system table, making data recovery an extremely complex and expensive process that requires special equipment.
Advanced cleaning via ADB and command line
For advanced users with access to USB debugging, there is a method for deleting files through a computer using the toolkit Android Debug Bridge (ADB). This method allows you to execute commands directly, bypassing the graphical interface, which can be useful when the system freezes or the touch screen is damaged. To work, you will need an installed device driver and a package of platform tools on your PC.
After connecting the phone and authorizing debugging, open the command line on the computer. To delete all photos from the standard camera folder, you can enter a command specifying the path to the directory. The command will look something like this: adb shell rm -r /sdcard/DCIM/Camera/*. This instruction forcibly deletes all contents of the specified folder. Be extremely careful with the syntax, as an error in the path can lead to the deletion of system files.
adb shell rm -r /sdcard/Pictures/*
adb shell rm -r /sdcard/DCIM/.Thumbnail
Using the console gives maximum control, but also carries the highest risks. An incorrectly entered command may damage the directory structure. In addition, on modern versions of Android with enhanced protection, access to some system folders may be limited even for ADB without receiving root access. Use this method only if you are confident in the command line and understand the consequences of your actions.
⚠️ Attention: ADB commands are executed instantly and cannot be cancelled. Before entering any deletion command, carefully double-check the specified file path.
Factory reset is the only way to ensure that all traces of personal information are removed before selling the device, including hidden caches and system logs.
Frequently Asked Questions (FAQ)
Can photos be recovered after emptying the Recycle Bin? in the gallery?
Recovery is only possible using special data recovery software, and even then not always. If, after deletion, the files were overwritten with new data, the chance of getting them back tends to zero. It is impossible to restore files from an emptied Recycle Bin using standard system tools.
Why is memory space not freed up after deleting a photo?
Most likely, the files remained in the “Trash” or “Recently Deleted” folder. Also check cloud storage services such as Google Photos: if sync is enabled, deleting on the device may not affect the cloud, but the app itself may cache thumbnails, taking up space.
Are photos deleted from the cloud if I delete them from my phone?
It depends on the sync settings. In the default Google Photos app, deleting a photo from your device may prompt you to delete it from the cloud as well. To avoid this, disable synchronization before deleting or use a file manager to erase local copies.
How to delete a photo if the phone screen is broken and does not work?
If USB debugging is enabled, you can use ADB commands from the computer. If your phone supports image output via USB-C to a monitor and a mouse is connected, you can control the interface visually. As a last resort, remove the memory card (if any) and read it through the card reader on the PC.
