Hi,
I’m interested in adding some data (A tag) to all the
files on the drive. no matter what format doc, ppt,
xls,pdf, txt etc etc… I want a tag to be added any
where in the file which my filter driver could read
and process the files in corresponding way.
Is this case addressed any where earlier in the forum,
I have searched but din’t find any thing.
I am looking for some suggestions to achieve this and
also some links which could explains me the procedure
of doing this.
TIA
Zoha.

Extended Attributes can be used to add hidden data to a file. Requires an EA
supporting file system.

If you can restrict yourself to NTFS, Reparse Points may be in option
(look these up in MSDN). Otherwise, you’re faced with adding a header to
the beginning of end of the file that your filter then ‘hides’ from
requestors (by lying about the file size and adjusting reads/writes/set
EOFs) - which is an enormously complicated task.

If its ntfs then you can use an alternative data stream?

It’s very broad question. Too broad to give any useful advice. Do you
want your “tag” to persist when you move/copy a file to another folder?
Another drive? Another computer? Do you want it to persist even if that
drive where you move file doesn’t have your filter on it? Do you want to
tag each and every file on disk? Some subset? Etc, etc, etc… Depending
on your answer you may use different techniques: from simply using file
ID/extended attributes/streams/WinFS (in future) to pretty [very]
complex systems that “inject” tags to the file content.

Yes, I want to achieve that, I want to add a
persistance tags to all the file. No matter where they
are existing. If the file is on a system which does’nt
understand my tag, it should not stop the file to work
in its desired way.

I wanted to tag every file on the disk, leaving
nothing.

Finally, how could the case be if I want files to be
tagged if and only if they are on the system where
they have My Filter driver, and if they are coppied
then i really don’t care.( I shall remove the tag when
they are being coppied)
Can i also get some links or good books or references
which talks about file tagging and headers at the
driver level.
