The deletion will be perment and you have no chance to recover it if you didn't take a backup. So the first step we should do before selling is making a fully backup of personal data, such as photos, documents, media files, etc. This step is conspicuous and crucial anyway.
If you are switching computers then you want to take all the files and folders from the old computer to the new one to avoid any data loss. Whether you copy all the important files to an external hard drive or upload all information on an online cloud server like Google Drive or Dropbox whatever makes it easier for you.
But you should store the files in a convenient location from where you can easily restore the files from. Most app and software comes with DRM Digital Rights Management technology that is only authorized in your own computer.
You must de-authorize every app and software from your old computer so that you can easily migrate them to the new computer. If you don't do this step, then you may have to end up purchasing the same software again on the new computer which will be a wastage of money. Computer is our main working force and we logged in with all kinds of services and apps, such as Microsoft account, Apple ID, Email or Adobe Creative Cloud.
You have to sign out the services from each app installed on the computer. You can't afford those kind of privacy being exposed to someone else becasue your credita card information, personal details, projects are stored on the computer.
Surfing the web has become the most frequent and important activity in nowadays. Internet is an integrated part of our daily life. So we can't live without a web browser, which saves all cookies and history locally. If we didn't clear it up, then the next owner will definitely login the website or service we ususally do. This is so dangerous! So you have to clear all browser cookies and history to avoid privacy leak. This is the final part of our story and it is one of the most important parts of this guide.
If your computer is using magnetic hard drive then it is possible to recover all data by using professional data recovery software since a simple data deletion or formatting the disk will not permanently erase the filefrom your computer. Toggle it on, and it will automatically delete files in the Recycle Bin after 30 days, and eliminate other temporary files, too. Our previous Storage Sense how-to is still in effect, but Windows has added controls to optionally delete files in your Downloads folder.
I never want that to happen, and you might not want that to happen, either. You can always go way down to the bottom of the Storage Sense configuration page and kick off Storage Sense manually. As my colleague Brad Chacos explains , WinDirStat solves this problem by offering a top-down view of your hard drive, with a graphical representation of the size and type of your files.
Want to find out how much space is consumed by. MP4 video files? WinDirStat can tell you. It presents this information to you in a File Explorer-like interface coupled with a graphical UI, so you may need to dig through and find any hidden Steam games, for example, that may have escaped your notice. That makes it difficult for cybercriminals to access or steal your information. You might think moving your documents to the trash or recycle bin and emptying it will do the trick.
Maybe not. This action appears to delete the files, but often leaves them where they were, hidden from view. Most data recovery programs can actually recover these hidden files.
When you empty files from the trash or recycle bin, the file name or the reference to the deleted file is erased. The computer can no longer see the file. This means the space the file took up on the laptop or PC is no longer reserved for that file.
But the file is still in the hard drive. It will stay in the hard drive until its location is given up for a new file to be stored in that exact location. Data recovery software is capable of rebuilding the file header. This makes it possible for the computer to see the file again.
When your files are not deleted completely from the hard drive, cybercriminals can run data recovery software to access your deleted files. Law enforcement agencies use data recovery software to access deleted files from confiscated computers. Cybercriminals can use the same tools and techniques to commit identity theft.
Special software programs can permanently erase your hard drive. Similarly, no one else will be able to use data recovery software to recover your files.
Most programs run a low-level format that overwrites all the deleted files with zeros and other incomprehensible data. This makes it impossible for data recovery software to recover the files.
This includes all personal files, operating systems, and installed programs. Most products offer proof of erasure. Some even provide information about what was done to the drive and its data. This helps when wiping a company laptop or PC. If you want to double-ensure your hard drive is wiped, you can take additional measures. For instance, you can physically wipe the drive. Just remove your hard drive and take a rare earth magnet to it.
Another option? Physically dismantle it with a screwdriver. A rare earth magnet, like the neodymium magnet, can be used to deform the metal plates in the hard disk.
This makes it unusable. One warning: The magnets are powerful and can cause physical harm if used incorrectly. A safer method might be using a screwdriver to dismantle the pieces of the hard drive to make it useless.
