Laurie, you miss the point. It does not just delete the file/folder/etc without putting it in the trash can, it also OVERWRITES that area on your disk, MULTIPLE times, with securely created 1's, 0's, and random patterns making it impossible to recover. Files deleted, even not in your trashcan, CAN be recovered if the recovery is done immediately and partially recovered if there has not been much disk action (so as to reuse the disk area previously occupied by the deleted file. From their web page: "Government & military erasure standards including DoD 5220.22-M, Peter Gutmann's algorithm, etc."

Laurie, though Windows warns you that pressing shift+delete will permanently delete your file, actually the file is not deleted. Windows just removes the filename from the Folder listing and marks the areas that the file occupies, as "free".

Later, when you (or Windows) saves files, depending on the free space available and other factors, it may use some of these so-called "free" locations.

So, since the file contents are not actually deleted, it is possible to get back or recover a deleted file using special undelete programs or file retrieval tools.

Programs like today's DoYourData Super Eraser overwrite these locations with random data, thus making it impossible to recover your file contents.

This is usually not important for us normal users unless you work with super confidential information that "should not get into the wrong hands".
