Index folders and file structure

Concerning Dropfiles. I have a large quantity of pdf's and jpg's that are already categorized in folders and sub-directories that I plan to ftp to the joomla 4 server. I do not want to re-create this file structure in joomla and then import the files in respectively it will take me a year. Will this program index the folder and files structure that I ftp in to joomla and create the folders for me so I can have it as a front-end viewer? If not this program, do you have recommendations. I bought edocman and it does not have these features which was disappointing. Appreciate your feedback.
