Recovering deleted files from a flash drive on Android: a complete guide 2026

Have you deleted important files from a flash drive connected to an Android smartphone and don’t know how to get them back? This situation is familiar to many: photos, documents or videos disappear after accidental formatting, system failure or unsuccessful copying. Fortunately, in 90% of cases, data can be recovered - even if you have already formatted the drive or emptied the recycle bin.

In this article we will examine 5 proven methods getting back deleted files from a flash drive on Android - from simple built-in tools to professional apps. You will learn how to proceed, what applications work with without root accesswhat applications work with USB-OTG i microSD, and what to do if standard methods do not help. Important: the sooner you start recovery, the higher the chances of success - new data can overwrite deleted files.

The material is suitable for all versions of Android (from Android 8.0 Oreo to Android 15) and any types of flash drives: USB Type-C, microSD, OTG adapters. If you Samsung, Xiaomi, Realme or another brand, the instructions are universal. Let's start with preparation.

1. Preparing for recovery: what needs to be done BEFORE starting the procedure

Before trying to return files, follow 3 critical stepsto avoid aggravating the situation:

• 🛑 Immediately disconnect the flash drive from the phone. Any write operations (saving photos, installing applications, caching) can overwrite deleted data.
• 📵 Do not connect the drive to other devices —especially for Windows/Mac. Operating systems automatically create service files (for example, Thumbs.db or .DS_Store), which overwrite lost data.
• 🔋 Charge the phone by at least 50%. The process of scanning a flash drive can take from 20 minutes to several hours - interruption due to low battery will reduce the chances of recovery.

If you have already connected the flash drive to the PC or saved new files to it after deleting it, the probability of successful recovery drops by 30-70% it depends on the amount of overwritten data. In such cases, you will have to use deep scanning (we will talk about it in the section about DiskDigger).

⚠️ Attention: If the flash drive is physically damaged (not detected by the system, makes sounds when connected, heats up), do not try to recover data programmatically. This can lead to complete if the drive fails, contact a service center with equipment for chip-off recovery.

2. Recovering through the Android recycle bin (if files were recently deleted)

Many users do not know what Android has hidden recycle bin —not as obvious as on Windows, but it retains deleted files for 30 days (depending on the manufacturer). This method works if:

• 📁 Files are deleted through the standard application Files (from Google) or My file (on Samsung).
• ⏳ No more than 30 days have passed since deletion (for some brands, for example Xiaomi, the period is reduced to 15 days).
• 🗑️ You did not empty the trash manually through the app menu.

To check cart:

1. Open the application Files (blue folder icon) or My file (on Samsung).
2. Tap in the upper left corner to ☰ → Recycle Bin (or Deleted files).
3. Select the required files with a long tap, then press Restore (up arrow icon).

If the recycle bin is empty or is not in the menu, proceed to the next method. Please note: the recycle bin in Android does not back up files from external drives (flash drives, SD cards) - only from internal memory, this method is only suitable if you deleted files directly through the phone, and not on them. PC.

3. apps for recovering files from a flash drive on Android

If the recycle bin does not help, it’s time to use specialized utilities. We tested 12 applications and selected 3 most effectivethat work without root and support flash drives via OTG:

Let's look at each in detail.

3.1. DiskDigger - the best choice for photos and videos

DiskDigger is the most popular file recovery app on Android. It supports all types of flash drives (including microSD and USB-OTG) and works without root, although with superuser rights the efficiency is higher.

Instructions:

1. Install DiskDigger from Google Play.
2. Connect the flash drive to the phone via an OTG adapter.
3. Launch the application and select Full scan (required for flash drives!).
4. Specify the file system of the drive (usually FAT32 or exFAT).
5. Wait for the scan to finish (may take up to 1-2 hours for a 64 GB flash drive).
6. Mark the found files and click Recover. Save them to internal memory or cloud.

⚠️ Attention: The free version DiskDigger allows you to recover only low-resolution photos and videos for documents, archives and full-size media files. needed Pro version (cost ~300 ₽).

3.2. Recuva via Termux - for experienced users

If DiskDigger did not find the necessary files, you can run Recuva (a popular PC app) directly on Android through an emulator Termux. This method requires root accessbut finds 20–40% more data than mobile utilities.

Instructions:

1. Install Termux and update packages:

   pkg update && pkg upgrade

2. Install Recuva via proot-distro (Linux emulator):

   pkg install proot-distro
   proot-distro install ubuntu
   proot-distro login ubuntu
   apt update && apt install recuva

3. Connect the flash drive and find its path in the system:

   ls /storage/

   (usually this /storage/USB_OTG_1 or /mnt/media_rw/...)

4. Run Recuva and specify the path to the flash drive for scanning.

This method is more complicated, but it is the only one that restores installers and rare formats (for example, system files, .apk-installers and rare formats (for example, .psd or .raw). Read more about setting Termux read in spoiler below.

apt install wget x11-apps

wget https://www.piriform.com/recuva/download -O recuva.deb
dpkg -i recuva.deb

apt --fix-broken install

3.3. Dumpster - an alternative for multimedia

Dumpster is not a classic recovery application, but automatic recycle bin, which backs up deleted files in the background. If you install it to data loss, the chances of getting your files back are close to 100%.

How to use:

1. Install Dumpster and enable autorun in Android settings.
2. The next time you delete files, they will automatically go to Dumpster.
3. To restore, open the application, select the files and click Restore.

Cons: does not restore documents (.docx, .pdf) and does not work with files deleted on the PC. But does not require root and free.

4. Recovery via PC: when Android applications do not help

If mobile utilities fail, connect the flash drive to the computer and use desktop apps. They are more powerful due to direct access to the file system. The best options:

• 🖥️ R-Studio —recovers files even after formatting (supports FAT32, exFAT, NTFS).
• 💾 EaseUS Data Recovery —simple interface, finds more than 1000 file formats.
• 🔍 PhotoRec —free utility for deep scanning (works via the command line).

Instructions for R-Studio:

1. Connect the flash drive to the PC via a card reader or OTG adapter.
2. Run R-Studio and select your drive in the list of drives.
3. Click Scan and specify the file system (if you don’t know, leave Auto-detection).
4. After scanning, mark the files for recovery and save them to another drive (not a flash drive!).

Advantage of the PC method: apps see raw sectors drive, which increases the chances of success. For example, PhotoRec ignores the file system and searches for data by signatures, so it recovers files even after full format.

⚠️ Attention: If the flash drive is formatted in NTFS (rare, but it happens), standard Android applications will not see it. In this case required use a PC with Windows or Linux.

5. Manual recovery via ADB (for advanced)

If you have root access or enabled USB debugging, you can try to extract files via ADB (Android Debug Bridge). This method is suitable if:

• 🔧 The flash drive is detected by the system, but the files are not displayed.
• 📂 You need to restore specific files (for example, config.ini or database.sqlite).
• 🖥️ You have a PC with installed ADB Tools.

Instructions:

1. Connect the phone to the PC and enable USB debugging (Settings → For developers → USB debugging).
2. Open the command line and check the connection:

   adb devices

   (the serial number of the device should be displayed).

3. Get a list of connected drives:

   adb shell ls /storage/

   Find your flash drive (for example, /storage/1234-5678).

4. Copy the necessary files to the PC:

   adb pull /storage/1234-5678/DCIM/photo.jpg C:\Backup\

This method requires knowledge of the command line, but it allows extract files bypassing the file systemFor example, if the flash drive is damaged and Android does not see it, but the PC identifies it as a RAWdisk, ADB may help.

adb shell ls -la /storage/1234-5678/

Flag -la shows all files, including system ones.-->

6. If all else fails: professional services

When software methods fail work, all you have to do is contact data recovery laboratoryThis is relevant if:

• 💥 The flash drive is physically damaged (the chip burned out, the connector is broken).
• 🔄 The data has been overwritten many times (for example, after full formatting).
• 🔒 The files are encrypted or password protected.

The cost of services depends on the type of damage:

Where to look for services:

• 🏢 Official centers (for example, Kaspersky Lab or Hetzner Recovery).
• 🔧 Local workshops (check reviews on Yandex.Maps or 2GIS).
• 📦 Posting (for example, in ACE Lab or R-Studio Agent).

⚠️ Attention: Before contacting the service do not try to recover data yourself —every unsuccessful launch of apps reduces the chances of success. It is better to pack the flash drive in an antistatic bag and take it to specialists.

7. How to prevent data loss in the future

To no longer encounter the problem of deleted files, follow 5 rules security:

• ☁️ Automatic backup. Set up synchronization of the flash drive with Google Drive, Yandex.Disk or Syncthing (free software for local backup).
• 🔄 Proper extractionAlways use Safe removal in the Android notification menu to avoid file system corruption.
• 🛡️ Virus protection. Install an antivirus (for example Malwarebytes) and scan the flash drive after connecting to other people's devices.
• 📂 Data separation. Store important files on a separate flash drive (for example, SanDisk Ultra with high write speed), and temporary files on another.
• 🔧 Checking the health of the drive. Once every 3 months, test the flash drive for errors via H2testw (PC) or A1 SD Bench (Android).

If you often work with important data, consider buying a flash drive with hardware encryption (for example, Kingston IronKey or SanDisk SecureAccess). They protect data even if the drive is physically lost.
