![]() ![]() Running a low-level format or another utility that overwrites all deleted files with zeros or other garbage is the only method of making sure files cannot be recovered. It’s faster for a computer to remove the reference to a file versus instructing the hard drive to overwrite the file with other data. This software only works if no other file or data was saved over the top of the deleted file. However, the file remains on the hard drive until another file or part of another file is saved to the same location.īecause the file is technically there, it may be recoverable using data recovery software to rebuild the file header, allowing the computer to see the file again. ![]() What does this mean? The file is no longer readable by the computer. The space the file took up is no longer reserved for that file, and any new file can be stored in that location. Once the file header, or reference, is removed, the computer can no longer see the file. When a computer deletes a file or the Recycle Bin is emptied, it’s removing the reference to the file on the hard drive. Once it is emptied, that disk space is recovered. Because the files are not marked for deletion, they still occupy disk space when stored in the Recycle Bin. Do files in the Recycle Bin occupy disk space? Later, when you empty the Recycle Bin or Trash, the icon changes back to an empty trash can and the files are deleted. When something is sent to the Recycle Bin or Trash, the icon changes to indicate it contains files and if needed allows you to recover a deleted file. When you first delete a file, it is moved to the computer’s Recycle Bin, Trash, or something similar depending on your operating system.
