Recover deleted photos from internal storage with DiskDigger
Accidentally deleting an important photo is one of the most common mistakes in everyday life, but it rarely means permanent loss.
What happens when a photo is deleted from a cell phone?
When you tap “delete” in the gallery, Android removes the reference to the image from the file table. The photo will no longer appear to you, but the original data remains stored in the device's flash memory. This applies to both internal storage and the SD card.
The system interprets that space as free. Any new record, app, music, or screenshot can be saved directly over the old data. When this happens, recovery becomes much more difficult. Therefore, the first step before any attempt is to stop using the phone as soon as possible.
The challenge with internal storage is that Android protects the main partition for security reasons. On many devices, neither the user nor apps have direct access to unallocated memory blocks. It is precisely in this scenario that specialized tools like DiskDigger stand out.
What is DiskDigger?
DiskDigger is a data recovery application for Android that performs a direct scan of the device's file system. It reads the raw storage content and searches for signatures of known images, such as JPEG, PNG, GIF, and WebP files, even when the file name no longer exists.
The idea is simple: map the areas of memory that still contain fragments of deleted photos and reconstruct them. It works with both memory cards and internal storage, and is widely used by those who need to recover lost photos without resorting to a computer.
In addition, DiskDigger has two main scanning approaches. Quick scan checks media files that are still accessible by the system. Deep scan, available on rooted devices, searches more sensitive areas of memory where old photos tend to remain.
What image formats can DiskDigger recover?
DiskDigger is able to recognize the most common formats used by current smartphones. This greatly increases the chance of recovering lost photos, regardless of the image's origin.
- JPEG files from the cell phone camera
- PNG images captured in screenshots
- GIFs received in messaging apps
- WebP is widely used for downloads and sharing over the internet
- RAW images, depending on the device and shooting mode
- Cached photos from social media and browsers
The more complete the file, the more thorough the restoration. The app can recover everything from thumbnails to high-resolution images, depending on the state of the memory.
Requirements for recovering deleted photos from internal storage
Before you begin, it's important to confirm that your device meets the basic requirements for using DiskDigger. The absence of any of these items may prevent scanning or reduce the chance of success.
- Device with updated Android operating system
- Permission to access media and device storage
- Free space to save the recovered photos
- Sufficient battery for a long scan
- Optional: Root access for deep scanning of internal partitions
If your phone isn't rooted, DiskDigger can still perform a useful scan of the media storage areas. In many cases, recently deleted photos are found even without special privileges.
Step-by-step guide to recovering deleted photos with DiskDigger
To get a good result, you need to follow a logical sequence. This prevents new data from overwriting the photos you want to recover and increases the tool's efficiency.
Stop using the device immediately
As soon as you notice the deletion, stop all other activity on your phone. Do not open the camera, browse social media, or receive calls. Each new recording in the memory can permanently destroy a deleted file.
Turn on airplane mode to block notifications, messages, and calls that may generate data. If the device is syncing files to the cloud, also disable the internet connection.
Install DiskDigger on your mobile phone
For those who don't already have the app installed, use the official DiskDigger page on the Google Play Store. Be wary of modified versions or apps with similar names in alternative app stores.
During installation, Android will inform you which permissions the app needs to access. Read the warning and continue only if you recognize the legitimacy of DiskDigger.
Grant access to internal storage
When you open DiskDigger for the first time, the system will ask for permission to access the device's media. Tap "Allow" or "Allow access," depending on your Android version.
On newer phones, a specific screen may appear requesting access to all files. Enable this option so that the scan reaches the internal memory folders.
Select the scan type and directory
On the DiskDigger home screen, tap “Search for lost photos.” Then, choose between quick scan and deep scan.
For recently deleted photos, a quick scan usually yields results. Then, navigate to the root of the internal storage, generally represented by the names "Internal memory" or "Memória interna".
Please wait for the analysis and identify the photos found
Scanning time varies depending on the amount of data on the phone and the speed of the memory. On some devices, the analysis can take from a few minutes to more than an hour.
Meanwhile, DiskDigger displays the progress and compiles a list of located thumbnails. Many images appear without names, only with a preview and approximate size.
Select the photos and save them to the correct destination
After scanning, tap and hold on the thumbnails you want to recover. Use multi-select to restore the entire folder at once.
Next, tap the recovery button and choose the best destination. If possible, save the photos to another folder on the same device or upload them to a cloud service. Avoid saving directly to the same area where the files were deleted, as this can cause conflicts and overwrites.
Time is a crucial factor in recovery
There is no exact time frame for a photo to disappear from a cell phone's memory. On devices that are rarely used, the data may remain intact for weeks. On frequently used phones, the photo may be overwritten in a matter of hours.
What determines success is not the time elapsed since the deletion, but rather the amount of new data written after the incident. The sooner DiskDigger is used, the lower the chances of irreversible damage.
After accidental deletion, avoid downloading apps, updating the system, or even taking new photos. These common actions are the biggest culprits in making recovery impossible.
What should I do if DiskDigger can't find the photos?
There are situations where the scan does not return the expected result. This can occur if the photo storage space has already been overwritten, if the deletion was done by formatting, or if the device's system has restructured the file table.
In this case, try another deep scan with the device plugged into power and check if the model supports root access. You can also test DiskDigger with a USB cable connected to a computer, if the application is available for your platform.
Avoid installing multiple recovery apps at the same time. Each new installation can write data to memory and reduce the chances of a successful initial scan.
