Different Options
This guide offers two different installation options: full and partial. The full installation will install the Pantheon-Files plugin, the panel icon, and system folders. This is the correct option for someone who hasn't used the guides mentioned above.If you already have the plugin and panel icons installed (or you don't want/need them), you will want to do the partial installation option. This option will only install the system folders.
Installation
Download the appropriate package above and unpack it.With the terminal, navigate into your extracted folder. For example, if you unpacked your folder inside the Downloads folder, your terminal code will look like this:
cd ~/Downloads/elementary-dropbox-integration/
Once you are inside your folder, run the installation.
chmod +x install.sh ; sh install.sh
You may need to logout and login for changes to occur.
Problems
There are a few problems. We think these are minor, but you will want to decide that for yourself.The first bug is the spacing of the folders in the home directory. They appear pushed together.
The second bug is found inside the open/save dialogue. As mentioned in our warning above, this entire hack makes use of the Desktop folder in an innovative way. Inside of the open/save file finder, the Dropbox folder is instead labeled Desktop.
