How to find all files with a particular parent directory in linux?

Question

How do you find all files with a particular parent directory in the linux command terminal?

I know to find all files using find like so:

find . -name filename.extension

But is it possible to find all filename.extension files with the parent directory of foldername?

I have tried the following but this does not work:

find . -name foldername/filename.extension

And I cannot find any example of how to do this.

So some example results I would expect are as so:

./example/project/website/foldername/filename.extension
./folder/demo/foldername/filename.extension
./more/files/foldername/filename.extension
./business/assets/foldername/filename.extension
./steven/foldername/filename.extension

Is there anyway to do this?

Answer 1

Use -path switch with find

find . -path \*/foldername/filename.extension

Answer 2

Just try this

locate "/*/foldername/filename.extension"
