True Delete - Irrecoverably Destroy Files and Folders to Make Them Unrecoverable and Unrecognizable.

This section discusses the True Delete functionality of the Eraser module.
The True Delete functionality irrecoverably destroys data and changes the properties of true deleted files and folders so that they become unrecoverable and unrecognizable. As described in the introduction to the Eraser module, when files and folders are deleted they are simply moved to a dedicated folder called the Recycle Bin. The Recycle Bin is pretty much a normal folder, except in that it is used by the system to store "deleted" files and folders. This allows deleted files to be restored easily before the Recycle Bin is emptied by simply moving the files out of that dedicated Recycle Bin folder. However, after emptying the Recycle Bin, it appears as if the files and folders are indeed deleted since they are no longer visible and their sizes are no longer accounted for. In reality, when the Recycle Bin is emptied, the deleted files and folders are only renamed using a forbidden character and thus they are marked as deleted and no longer considered as valid files and folders. However, their entire contents are still on the drive and over time, as new data is stored on the drive, parts from the "deleted" files are gradually overwritten. Thus, until completely overwritten, deleted files could be partially or fully restored using suitable software. As mentioned in the introduction, it is possible that even when overwritten, information may be still recoverable unless it is Truly Deleted. For drives which do not support Recycle Bin folder, the normal delete operation works in the same manner but without temporary storing the files in a dedicated Recycle Bin folder.

True Delete is important to use and truly destroy any deleted information whenever handling sensitive data. Even when sensitive information has been stored encrypted, it is good practice to delete it using the True Delete functionality so that files cannot be recovered and stopping the possibility of any future decryption attacks.

Operation Controls
True Delete Operation Controls
These controls determine the operation and behavior of the functionality.
OverwritesEnter the number of times to overwrite the data of any file being deleted with continually generated random data. In the process of true deletion, files are enlarged with a small random size and all file attributes including file-times, filename and extension are also changed randomly. Thus, true deleted files and folders are both unrecoverable and unrecognizable. The number of overwrite passes is from 1 to 255.
