FTP and Plex files

[Aramis]

Hello, I have two questions: is it possible to provide access to our libraries via FTP? Will it be possible to modify the existing libraries, for example, by removing photos and leaving just three libraries such as movies, series, and anime?

You would be able to access your files via smb not ftp. Top level folders would not be able to be deleted from smb but will be able to be deleted in hexos ui.
You can delete photos folder if you so felt like it. I imagine once 1.0 rolls out it would not cause any issues but beta hexos likes to freak out when thigns are different from what it expects. 
I can't say for certain it will or won't freak out without trying it tho.
