Solution 1: Delete Files in Windows 10
Usually, when mentioning cleaning data on hard drive, most of you choose to delete all data on the hard drive. You may spend much time going through the entire hard drive and deleting all personal files and documents you want to delete, but this way can't completely delete all data ,which are not safe to privacy information. Why?
In fact, the data on your hard drive is not deleted, and the information is stored in the directory that Windows operating system can find. When you delete a file, actually it means only removing the file from the folder, and this part is marked as a location that new data can be written to. In other words, the data in this part is always there, just the operating system marks it "deleted".
Therefore, before writing new data to the location, the original data can be restored. This provides a good chance to some data recovery software which can directly read the data which is labeled as "deleted" from the hard drive and then recover to the specified directory.
Note: In order to avoid data recovery, you can write new irrelevant data to the location after deleting data, so it is safer to your personal information.

If you format all partitions, this operation doesn't erase the data on the hard drive, just delete the address tables. This may be more difficult to recover the files of the disk. Whereas the professional tools are able to help recover most data before reformatting the disk. This is a good thing for you if you accidentally format a partition, you can recover data.
