It usually happens that we have a file in our system that makes us think from where did it come from? Or even that you are unable recall from which package did this file came?
If this is a common problem with you then just install the dlocate utility that is a good way to find the answer. Use the following command to install it
sudo apt-get install dlocate
Now to get information about the file, use the following command
This will provide you with all the info about the file. See the following example:
$ dlocate flac
All the files are listed that partially match the given file name, so to gain info about a particular file, just give its whole location in the filename.
