How to permanently delete files in English？
In today's digital age, data privacy and security are paramount. One of the most common concerns is how to permanently delete files to ensure that they cannot be recovered. This article delves into the intricacies of permanently deleting files and provides you with a comprehensive guide on how to do so effectively. Whether you're looking to free up space on your device or protect sensitive information, this guide will equip you with the knowledge to achieve your goals.
Understanding Permanently Deleting Files
When you delete a file from your computer or device, it doesn't disappear forever. Instead, the file's data is marked as available for overwriting. This means that until the data is overwritten, it can potentially be recovered using specialized software. To ensure that your files are completely gone, you need to overwrite the data with random characters.
Methods for Permanently Deleting Files
There are several methods to permanently delete files, each with its own advantages and limitations. Let's explore some of the most common methods:
1. Using the Delete and Empty Trash Option
This is the most straightforward method and is available on most operating systems. Here's how to do it:
- Windows: Select the file you want to delete, right-click, and choose "Delete." Then, open the Recycle Bin, right-click on the file, and select "Empty Recycle Bin."
- macOS: Select the file, press the "Delete" key, and then open the Trash, right-click on the file, and select "Empty Trash."
While this method is simple, it's not guaranteed to permanently delete files. The data can still be recovered using specialized software.
2. Using File Shredding Software
File shredding software is designed to overwrite the data on a file multiple times, making it nearly impossible to recover. Here's how to use it:
- Download and install a reputable file shredding tool.
- Select the file you want to delete and initiate the shredding process.
- Follow the prompts to complete the process.
Some popular file shredding tools include:
- Eraser: A free and open-source file shredding tool for Windows.
- ShredIt: A paid file shredding tool available for Windows, macOS, and Linux.
- File Shredder: A free file shredding tool for Windows.
3. Using Secure Erase Commands
Secure erase commands are available on some operating systems and devices. Here's how to use them:
- Windows: Open the Command Prompt as an administrator, type
sdelete -z [file size], and press Enter. - macOS: Open the Terminal, type
shred -u /path/to/file, and press Enter.
This method is more technical and may not be suitable for everyone. However, it can be effective in permanently deleting files.
4. Using Disk Wiping Tools
Disk wiping tools are designed to overwrite the entire disk, ensuring that all data is completely erased. Here's how to use them:
- Download and install a reputable disk wiping tool.
- Select the disk you want to wipe and initiate the wiping process.
- Follow the prompts to complete the process.
Some popular disk wiping tools include:
- DBAN (Darik's Boot and Nuke): A free disk wiping tool that can be booted from a USB drive.
- CCleaner: A paid disk wiping tool available for Windows and macOS.
