When we delete a file, we only delete one reference to the location of the file. In other words, the file system simply "forgets" the existence of the file. But the actual data, 0 and 1, still remain on the disk. They will eventually be replaced by other files and data, but this can take a long time and during this time the recovery software can be used to recover the "deleted" files. However, file shredding applications, such as Permadelete, ensure that the files you delete cannot be recovered.
