Replace accordion list [on hold]

Do you have any solution in mind for the following problem? Consider the following scenario: I have a lot of files arranged in folders( a lot of folders will be there), and I want to search for a specific file or folder. As we have now, if I extend an dropdown, I will have a list of over 100 files, and it is hard for me to scroll so much ( maybe pagination works better, but how to put pagination in this accordion?).

The button export.cvs is exporting the entire list.
