Looking for file browser /w remote login (OSX) & streaming

I was wondering if anyone of you can recommend me a good file browser for my iPad that allows me to do the following things:
1) Have access to my files on other OSX systems (remote login)
2) Stream audio and video content, open photos, edit text files (without having to download it first)

I tried Documents by Readdle and it seems perfect except that I have to download files before I can open them. Is this even possible?

 

That option came to my mind as well, but it has 2 limitations:
1) Size of iCloud drive (5GB free, but I would like to access my research data which is a lot more than that)
2) I need to have all the data saved also on my phone/tablet (not possible)

I just need to look at some graphs and plots on my tablet without having to download the whole folder structure.
