ISO Plugin to use a hidden page in website to drop files in/out like dropbox

I have a computer repair website, in theory, I would like a certain page (that would be passworded, just given to employees) to act just like a folder like dropbox,google drive, etc. Is this possible?

I could just add links, but with this idea, I could “drop in and take out” files from any location without loging into wordpress just accessing the hidden page, also any of my employees could do this as well (they do not have access to my wordpress)

I would like this so I could add virus removal programs and other daily used programs, to help when out on the road
