+   For Secure FTP (sftp), use of identity files is possible. Put both the **id_rsa** and **id_rsa.pub** into a folder in the PS4 hard drive. Then in the password field in the UI, instead of putting a password reference the folder where id_rsa and id_rsa.pub is place. Prefix the folder with **"file://"**

+   Example: If you had placed the id_rsa and id_rsa.pub files into the folder /data/ezremote-client,

  - Transfer files back and forth between PS4 and FTP/SMB/WebDAV server
  - Support for connecting to Http Servers like (Apache/Nginx,Microsoft IIS, Serve) with html directory listings to download or install pkg. 
  - Install Remote Packages from connected WebDAV server
+ - Ability to connect to your "Google Drive" to transfer files back and fort. Can also install packages from it. The app will download the file to the PS4's harddrive and then install it. You need to keep the app opened. Here is a link to the wiki for what you need to do to make it work. Also able to access files that are shared to you.
  - Install Remote Packages for FTP/SMB if HTTP server setup on same host sharing same folder as FTP/SMB
    - If Remote Package Install is not possible, optionally the user can choose to download package to PS4 local drive and install
  - Install packages from PS4 local drive **/data** folder or usb drive **/mnt/usbX**
  - Install package from Direct Links. Direct links are links that can be reached without being redirected to a webpage where it requires capthas or timers. Example of direct links are github release artifacts. Google shared links is the only exception since I could indirectly parse the webpage to obtain the direct links
  - Create Zip files on PS4 local drive or usb drive
  - Extract from zip, 7zip and rar files
