Delete and purge question

[Guest 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.

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.
