I noticed your question.
Been doing research into file recovery
It isn't for the particularly challenged PC user,
but freeware exists that
will restore deleted files.
Based on the fact that files that are placed in the recycle bin are not "wiped",
but merely the initial identification of them is modified, in winXP file systems,
and until & or unless they are actually "overwritten", they remain intact.
Practical use of the (these) freeware needs to be explained beyond what the help
within the program states, I'm finding.
the partition where the deleted files exist (typically your C:\) can not be the partition
from where the program is run.
Ideally you would have two separate HDs, one for system files (C:\) and the other for
perhaps your program files, data stored, large files like those for movies or music, etc.
It also works to have the single HD set up to have, as mentioned, more than one partition.
Windows would "see" perhaps a C:\, a D:\ and an G:\ if three partitions were used
in place of your present C:\
Unfortunately, setting the present HD up this way would involve reformatting it.
That would require wiping the drive, starting all over with a fresh installation of winXP.
You could simply buy another HD and install it, instead.
The software typically included with such a retail purchase (at say 50.00 - 100.00) will allow
you to partition the new (non-system) HD anyway you choose.
Anyway you do it, you will necessarily be required to:
1. Reveal the fact you are interested in learning more about your PC.
2. Do something about that interest.
3. Actually understand what you are doing.
Any of which might indeed be a general hint to the party whose use of it you question.
Perhaps a good thing?
Let us know how to assist further.
