When you delete a file from your computer, it moves to the Windows Recycle Bin. You empty the Recycle Bin and the file is permanently erased from the hard drive. ... Instead, the space on the disk that was occupied by the deleted data is "deallocated."
Where do they go after deleting the files or folders from the computer's recycling bin?
When you delete files from the recycle Bin or permanently delete them using the Shift + Delete command, the file name entry is removed from the Recycle Bin folder. The part of the disk where the file was located initially is then modified or overwritten but still contains the file data.
