A common misunderstanding when we delete files from computer is that they are completely removed from the hard disk? However end user should remember that highly confidential data can be retrieved from the hard disk using various tools even after the files are deleted because data is not really gone.
When user delete files from their computer still those files are available in recycle bin and if user delete recycle bin then users are under impression that my highly confidential data is gone forever but they are still located in the hard drive and can easily retrieve.
The only way to completely delete or erase file with no traces is using “Eraser Tool”
which is freeware and available to download on below URL:

There are various ways to delete, which are as follows:
1] Select files or folders in windows explorer and perform drag and drop them to the list
