File deletion

File deletion is a way of removing a file from a computer's file system.
The reasons for deleting files are
  1. Freeing the disk space
  2. Removing duplicate or unnecessary data to avoid confusion
  3. Making sensitive information unavailable to others
All operating systems include commands for deleting files (rm on Unix, era in CP/M and DR-DOS, del/erase in MS-DOS/PC DOS, DR-DOS, Microsoft Windows etc.). File managers also provide a convenient way of deleting files. Files may be deleted one-by-one, or a whole directory tree may be deleted.

Delete Files Permanently from your Computer

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. Right?

Well, the file appears to have been trashed but a skilled techie may have no trouble restoring that "deleted" file using data recovery software – some of which are freely available online. Here’s why:
When you delete files or folders, the data is not initially removed from the hard disk. Instead, the space on the disk that was occupied by the deleted data is "deallocated." After it is deallocated, the space is available for use when new data is written to the disk. Until the space is overwritten, it is possible to recover the deleted data by using a low-level disk editor or data-recovery software.
