Handling large number of files

Hey everyone,

I need to handle and display large amount of files (1000+) to the users. My plan is to have a member space where users would be able to access these files. They would chose what file they need (let's say from a series of drop-down menus) and that file must be displayed on the web page.
I could work with many formats (pdf, google docs, .txt...) so any solution would be appreciated. 

I am new to Squarespace, and I have been looking around for some time but I can't figure out if this is possible to do with the tools provided.
