Delete and purge question

[Sudy Nim]

Just curious, when something is emptied from recycle bin or purged using
w98se, where does it go? By that I mean can it be retrieve or is it actually
gone for good?

Any data deleted still exists on the drive.
It is simply marked as free space.

There are plenty of undelete utilities out there...
just not, that if you want to recover data...it can soon become
over-written...
so the sooner you try the recovery, the better your chances.

If you delete something by mistake...
your best option is to shut the machine down at once...
then slave the drive to another machine...
and recover the data from there

Files on the hard drive are listed in the File
Allocation Table as FILENAM.TYP (i.e. DOS
FN format) with the list of the drive sectors they
occupy. When deleted, the first char in the FAT
list is altered to lower case e i.e. eILENAM.TYP;
and the FAT recognizes that all the drive sectors
(still listed) are available when needed to write another
file, which will happen at some unpredictable time . . .

Thus UNDELETE utilities work simply by showing
you all instances of eILENAM1.TYP, eILENAM2.TYP
and so on, and inviting you to change the first char,
which restores the file i.e. reconnects its name with
all the sectors listed thereafter (whether overwriitten
or not.)

The space it occupies is added to the "empty space" chain. When new
files are created space is taken from this chain for them. So for a
while the data still exists on the disk, although there's nothing
pointing to it anymore. Eventually it will be overwritten by a new
file.

Re: Delete and purge question

I do not need to recover anything; I just wondered what happened to delete
files. Thanks to all for your clarification, I appreciate it.

You've gotten good answers, so I don't feel bad about asking a related
question.

What happens BEFORE something is emptied from the recycle bin?

Is its space NOT available?

If I go years without emptying the recycle bin, could I tie up all
potentially useful HD space there? Could I look at the drive
statistics and think I have filled my drive?

For years I assumed that it would take the files sent to the bin
longest ago and use their space when needed, but lately I'm not sure.

If you are inclined to email me
for some reason, remove NOPSAM

That's right.

The bin is set to occupy a certain amount of space on your drive.
Right-click the bin icon, select "Properties", look at the "Global"
tab. There's a slider which you can use to tell the system how much of
your disk space the recycle bin should take up. When adding another
file would exceed that space, the oldest file or files are deleted to
make space for the new one.

You were right in the first placed.

Yes, I see the slider.
