Why should you permanently delete files on your computer before selling?
Our computers contain a lot of personal data, including financial records, passwords, photos and private documents. If these data are not permanently deleted from the hard drive, they can be accessed by unauthorized people. This can cause unforeseen risks such as:
Bad guys can use your personal information to fake your identity, open bank or credit card accounts, or make fraudulent transactions.
Revealed private information
Your online activities, browsing history, and saved logins can reveal a lot about your personal life. Know how to wipe computer data pre-sale will ensure that your privacy is protected, preventing anyone from accessing your online accounts, social media profiles or private chats.
Can recover data
Deleting files using traditional methods like dragging them to the trash or formatting the hard drive will not permanently remove them. People with technical expertise can use specialized software to recover deleted files from hard drives, potentially exposing your sensitive information.
If you transfer your computer to someone else as part of a business equipment upgrade or when moving to a new job, do how to wipe computer data. Files related to work, customer data or proprietary information can cause damage if in the wrong hands. Permanently deleting these data will ensure that they cannot be recovered, protect your reputation and avoid any possible legal problems.
Steps to prepare for permanent deletion of files
Back up important data
Before deleting anything, you need to back up the important data you want to keep. Identify important files and folders, such as personal documents, favorite pictures, or work-related files. Copy them to an external hard drive or a cloud storage service, etc. That way, you’ll have a copy of the data in case you need it later.
Review files stored on your computer
Carefully evaluate which ones are necessary and which you can delete. Organize files by category or folder for easy identification. This way you will avoid mistakenly deleting files that you may still need.
Backup OS Product Key
If you are going to sell or give away your computer, be sure to back up the Product Key for your operating system. This key is needed to reinstall the operating system on a new device, saving you money from having to buy the key again when using it on another device.
Backup purchased software
If you have purchased any software applications or programs, take the time to back up the license keys. This will make it possible for you to reinstall them on your new computer.
Ways to wipe computer data before selling
After you have backed up your files, it’s time for you to choose an appropriate file deletion method. There are many ways to wipe data on your computer, such as:

Step 5: Choose how to reinstall Windows, you can choose any one
Step 6: Select “Change settings”
Step 7: In the “Choose settings” window, click to enable the “Delete files from all drives?” and “Clean data?”
Enabling these options will ensure that all data from your hard drive is permanently erased and cannot be recovered. Then, click “Confirm”.
Step 8: Continue to select “Next”
Step 9: Click “Reset” to begin the process of permanently deleting files on your Windows computer.

Step 1: Open Command Prompt
Step 2: Type “ cipher /w:FolderName ” and press Enter key. Replace FolderName with the name of the folder you want to delete its contents from.
