Finding Location of Nextcloud storage

[details=“Support intro”]
My IT guy set up Nextcloud but did not tell me where my data is stored. I think he may have put it on his network. He passed away. How do i find out where my data is stored?

Thanks for any help.

search in config/config.php for datadirectory

or, if you know the name of a file stored in nextcloud, search for it after login on console:

cd /
find -name <name_of_file>
