How to Delete document from Item but not Item itself

Question

Hello
I'm working on Oracle Portal (10g)
I'm thinking about one problem:
- how to physically remove document form the Oralce repository using PL/SQL
Does removing row from WWDOC_DOCUMENT$ remove file from hard disk (some
trigers on Delete?).
BTW:
There is one strange (for me ;) ) behavior: I create an item with atached
file (file item) what happent:
- in table WWDOC_DOCUMENT$ is new row for new file created.
- in table WWV_THINGS$ is new row for new item created
Now I would like to remove file but not item (still using PL/SQL).
I use function for example:
PORTAL.Wwdoc_Api.remove_document('101801.BMP');
This function remove path id and filename but not whole file row itself (but
this is less problem). And othere more important problem: after
PORTAL.Wwdoc_Api.remove_document called there is still in item rows pointer
to just deleted file in fields: FILENAME and VALUE.
I would like to set this fileds to null. - in othere way there is exception
durring page deletion (no document found).
I use:
update portal.wwv_things p1
set
p1.FILENAME = null,
p1.VALUE = null
where p1.ITEMTYPE like 'basetext'
and p1.LANGUAGE = wwctx_api.get_nls_language
and p1.SITEID = pagegroupID
and p1.CORNERID = pageID
and p1.filename like '101801.BMP' ;
But this seems to not work at all.
Any body else had some problems like me?
How it was solved.
BTW: I work with item versioning.
BIG THANKS YOU FOR ANY HELP

You can try my new DeDupe script. It should be able to get rid of the redundant copies while keeping one copy of each track in each format. See this thread for background.
I've not used the feature, but iTunes can downsample to 128k AAC on the fly as it syncs your devices. Of course you might find the process is too slow for your needs or find that 128k is too much compression.
