How to create a variable in env.rb or hook.rb and call in cucumber feature ?

Thank you in advance for help.

I am trying to create variable in env.rb

File_path =("#{File.dirname(__FILE__)}/../../features/TestData/Testdata.html")

and call File_path in the Cucumber feature directly.

for example
...
And I upload a file from path "<File_path>"
...

Is the is a better way of doing this ?
