phpbb forum files deleted but database safe. how to configure new files with the existing database?

I have been using a phpbb forum.

It got deleted.

The database is intact. safe.

What are all the files i should modify.

I hope it is mostly one config file.

what are all the configurations i need to change?

so that the new files will work with the existing database.

I forgot the version. may be i can read it from the database.

Anyway... I need a help to restore my project.

Solution

I found out the answer from phpbb forum.

it worked.

Here it is...

but still if people would like to comment or suggest then please do so.
