It has occurred to me that using the Recycle bins builds in a certain amount
of security not had without them.

By pulling files to localized places then deleting them, one gets a degree
of over-writing somewhat similar to military type high security repetative
over-writing.

Right?
 
You can hold down Shift, and bypass the Recycle bin.
It is there in case you make a mistake deleting files, and you want to
recover them easily.

Hello Jim:

Your point is not lost. However, without HDD defragmentation and/or
optimization, it might take a long time, and additionally problematic,
to overwrite the space where a sizable file had been.

A slight unforeseen benefit at best.

Wouldn't a DoD 5220.22-M erasure be much more dependable. Yes?

Wrong. The files are not actually deleted when you put them in the Recycle
Bin. The "pointer" that tells the file system where the files are located
is changed and that's all. When you empty the Recycle Bin, the "tag" that
tells the system not to write data to the location of those files is
removed. The files themselves still remain, which is why data recovery
software can retrieve them.

You may have noticed that moving (not copying) a file from one
directory to another is almost instantaneous if the two directories
are in the same file system (the drive letter is the same) while it
takes a noticeable amount of time (dependant on file size) when two
file systems are involved. The reason for this is that in the former
case, the file itself is not moved. Only the entry in the file system
control table (what used to be the FAT) is moved.

The Recycle bin is simply a special purpose directory. Putting
multiple files in the bin does not move the data from the files near
each other. Moving more files into the bin after deleting files does
not cause any overwriting.

What happens if the Recycle Bin is full when you delete a file?

If all the allocated space has been used, then the oldest file/s are
removed until there is room for the new deletion.

Probably not. The file may not be physically moved in this situation,
instead only the file table entries changed.

If you need to wipe files, use a wipe utility.

Then older items in the Recycle Bin will be deleted; i.e., the "tag" that
tells Windows not to write to the area of the hard drive currently reserved
for those files will be removed. However, if that area of the hard drive is
not overwritten by subsequent actions, the files will still be retrievable
with off-the-shelf data recovery software. That's why we tell people trying
to rescue deleted files to stop using the computer immediately, install the
recovery software on a different computer, create the recovery software
bootable CD, and boot the target machine with it.

Yes Malke I knew the answer to my question. The point of my question was
to get Barry Schwarz to reflect on what he had said.

Actually, as I said, it is just something that occurred to me - incorrectly
as it turns out. (That's what happens when the details handler in your
brain goes fishing and leaves the generalities handler on its own.)

Interesting subject though. I wish I could still wrap my mind around the
details. I used to know about several kinds of file handling. Anybody know
anything about the ancient Flex OS? Far superior file handling. Decades
ago it was set up so that files of any size up to the drive limit could be
handled.

Kinda like BetaMax. Better than VHS, but the bean counters bet their cash
the other way. Or the vast superiority of Motorola's OS's in memory
management, like Flex's superiority in file management. Not that OS/9+++
handle files shabbily at all. Wouldn't it be something if we could take the
best out of all the OS's and put them together to make something actually
good?
