"I just deleted a big file that is 5 GB in size in my Windows 10 desktop and the deletion only took about 10 seconds. Why is it so fast and is my file deleted securely?"
When you delete the big files/folders in Windows, it doesn't erase your data immediately. To enhance the work efficiency, Windows will release the space of the deleted data firstly and make the deleted data remove permanently through the new data's overwriting. In other words, your big file or folder isn't deleted securely with the quick and simple deletion.
To delete the big files or folders securely, which means that make the deleted files/folders unrecoverable, using a third-party tool is worth considering. And here we will take iSunshare File Deletion Genius as the file eraser to show you how to securely delete big files/folders in Windows 10.

Step 3: Select the deletion mode: Fast Mode or Slow Mode. Both of them can delete the big file permanently, so you can choose the one you prefer.
Step 4: After that, just hit the Delete button to begin forever erasing your big file/folder.
