Question: I am trying to portabilize every program I use if possible, and Notepad++ is on the list. The only problem is that I've had a native installation until now so that I'm not totally sure which settings files need to be moved to the portable directory.

Surely there's a function tucked away somewhere in NPP exactly for this purpose, or some plugin out there? I mean the developers have literally thought of everything else, yet this is the one thing I cannot find specifically anywhere in the NPP wiki or otherwise, and I don't want to miss an important file.

Here is the closest I've gotten: [Notepad++'s configuration files](http://sourceforge.net/apps/mediawiki/notepad-plus/index.php?title=Configuration_Files) and [Where are all the files?](http://sourceforge.net/apps/mediawiki/notepad-plus/index.php?title=Notepad%2B%2B_Install_Folder)

Should I just copy every configuration file listed on the first link?

Answer: 
Many settings in NP++ can be automatically kept in sync (and migrated) between multiple instances by using **Settings** > **Preferences** > **Cloud**

[![Preferences > Cloud](https://i.stack.imgur.com/Dh4n8.png)](https://i.stack.imgur.com/Dh4n8.png)

The first time you set a cloud location (which can just be any folder path), it'll backup your current settings into that folder and then draw from there going forward. When setting the cloud location on a new machine, it'll read in those files there. 

The cloud settings consists of the following items:

**Note**: You might need to remove the existing files with the same name under `%appdata%\Notepad++.` in order for the cloud storage files to take priority
You have already found the full list of Notepad++'s configuration files. If I were you, first I would copy the whole Notepad++ folder under the `Program Files`, and save it for some time. Then I'd start to use all the files listed on the [NPP page](http://docs.notepad-plus-plus.org/index.php/Configuration_Files), and after making sure everything's OK, I'd delete the backup.
