Use Case:

We currently already have implemented bulk file download. However it does not preserve the folder hierarchy of the files.

This can be troublesome for user to download if they have code which rely on the hierarchy.

Suppose a user had files:
/code/python/pythoncode.py

/code/R/rcode.r

/data/dataset1.csv

...

/data/datset/50.csv 

With the current bulk file download system, the user would get back a zip with all the files in the same directory. The user would then have to manually recreate the folder hierarchy, which could be troublesome of there were many files.
