**Why You Need to Permanently Delete Deleted Files on Android**

Why You Need to Permanently Delete Deleted Files on Android

There are several reasons why it is crucial to permanently delete deleted files on your Android device. Here are a few:

1. Privacy Protection: When you delete a file on your Android device, it is not immediately wiped from the storage. Instead, the reference to the file is removed, making it inaccessible. However, until the space occupied by the file is overwritten by new data, it can still be recovered. Permanently deleting deleted files ensures that your private files cannot be retrieved by unauthorized users.

2. Security: If your Android device contains sensitive or confidential information, such as financial or personal data, it is essential to ensure its complete deletion. Leaving traces of such data on your device can expose you to potential identity theft, fraud, or unauthorized access.

3. Storage Optimization: Deleting files permanently frees up storage space on your Android device, allowing you to make use of it more effectively. By permanently removing deleted files, you can optimize the performance and speed of your device.

Now that we understand the importance of permanently deleting deleted files on Android, let’s explore different methods to achieve this.

**Method 1: Factory Reset**

Method 1: Factory Reset

One of the most effective ways to permanently delete deleted files on Android is by performing a factory reset. A factory reset erases all the data on your device, including the deleted files, and restores it to its original state. Here’s how you can do it:

Step 1: Backup your important data: Before performing a factory reset, it is crucial to back up any important data or files that you want to keep. This will prevent any irreversible data loss.

Step 2: Open the Settings app: Go to the Settings app on your Android device.

Step 3: Navigate to System or General Management: The location of the reset option may vary depending on the Android version and device manufacturer. Look for System or General Management in the Settings menu.

Step 4: Select Reset or Factory Reset: Tap on Reset or Factory Reset to initiate the process.

Step 5: Confirm the reset: You may be asked to enter your device password or PIN to proceed. Confirm your selection by tapping on Reset or Factory Reset again.

Step 6: Wait for the process to complete: The factory reset process may take some time. Ensure that your device is sufficiently charged or connected to a power source during the reset.

Pros:
– Effective method to permanently delete all data, including deleted files.
– Restores your device to its original state.

Cons:
– Irreversible process; all data will be erased, including important files if not backed up.
– Requires re-setup of your device and reinstallation of apps.

**Method 2: Encryption**

Method 2: Encryption

Another method to permanently delete deleted files on Android is by encrypting your device. Encryption converts your data into an unreadable format and ensures that even if deleted files are overwritten, they cannot be recovered without the encryption key. Here’s how you can encrypt your Android device:

Step 1: Open the Settings app: Go to the Settings app on your Android device.

Step 2: Navigate to Security or Privacy: Look for Security or Privacy in the Settings menu.

Step 3: Select Encryption: Tap on Encryption or Encrypt Device to initiate the process.

Step 4: Set a secure password or PIN: You will be prompted to set a secure password or PIN. Choose a strong combination that is easy for you to remember but difficult for others to guess.

Step 5: Start the encryption process: Confirm your selection by tapping on Encrypt Device. The encryption process may take some time, so ensure that your device is sufficiently charged or connected to a power source.

Step 6: Complete the encryption setup: Once the encryption process is complete, follow any additional prompts to complete the setup.

Pros:
– Provides an additional layer of security for your data.
– Encryption protects deleted files from being recovered without the encryption key.

Cons:
– Encryption process may take some time and can affect device performance during the process.

**Method 3: File Shredder Apps**

Method 3: File Shredder Apps

File shredder apps are specifically designed to permanently delete deleted files on Android. These apps overwrite the storage space occupied by deleted files, making it virtually impossible to recover any data. Here’s how you can use a file shredder app:

Step 1: Install a file shredder app: Go to the Google Play Store and search for file shredder apps. Install a reputable and highly rated app that meets your requirements.

Step 2: Grant necessary permissions: After installing the app, launch it and grant the necessary permissions to access your storage.

Step 3: Select the files you want to shred: Choose the files or folders that you want to permanently delete. Most file shredder apps allow you to select individual files, multiple files, or entire folders.

Step 4: Initiate the shredding process: Once you have selected the files, initiate the shredding process. The app will overwrite the storage space occupied by the selected files with random data, making them unrecoverable.

Step 5: Confirm the shredding process: Depending on the app, you may be asked to confirm the shredding process. Follow the on-screen prompts to complete the process.

Pros:
– Specialized apps designed to permanently delete deleted files.
– Provides control over which files or folders to shred.

Cons:
– Requires the installation of a third-party app.
– Some file shredder apps may have limitations or require in-app purchases for full functionality.

**Method 4: Overwrite with Random Data via PC**

Method 4: Overwrite with Random Data via PC

In this method, we will use a computer to overwrite the storage space occupied by deleted files on the Android device. By transferring random data to the device’s storage, the deleted files become irretrievable. Here are the steps:

Step 1: Connect your Android device to a computer: Use a USB cable to connect your Android device to a computer.

Step 2: Enable USB debugging on your Android device: On your Android device, go to Settings, then Developer Options (or Developer Settings), and enable USB debugging. If Developer Options is not visible, go to About Phone and tap on the Build number seven times to unlock Developer Options.

Step 3: Open a file transfer program on your computer: Use a file transfer program, such as Android File Transfer for Mac or Windows File Explorer for Windows, to access your Android device’s storage.

Step 4: Select and transfer random data: Choose a large file or folder with random data on your computer. Copy or transfer this file/folder to your Android device’s storage, overwriting the space previously occupied by the deleted files.

Step 5: Repeat the process multiple times: To ensure the effectiveness of this method, repeat the transfer process multiple times with different random files or folders.

Pros:
– Overwriting with random data makes deleted files unrecoverable.
– Can be done using a computer, which provides more control and options.

Cons:
– Requires the use of a computer and a file transfer program.
– Multiple transfers may be time-consuming.
