Inserting query values from a text file

[Pipeops]

I am trying to create a query that is pulling text files from a local hard drive. Do you know what the root directory is so I can import the text file there and make my query work?

Postgres database is located on a windows server 2003.


update XXX.XXX
set XXXX = 'FALSE'
where XXX in ( select XXX from XXX.XXX where XXX in ('XXX.txt'))

If this is not the right way to do it, can you please point me to the right direction?

Thanks,
P
