I want to transfer N++ files to another PC.
- 
Files I’m looking for include:
- Preferences
 - Style Configurations
 - User defined languages

Did you read the User Manual page on Config Files, which includes a section on Config File location? If not, I suggest you start there. But the essential answer is “it depends on your current Notepad++ settings where the files are”, though they are normally in
%AppData%\Notepad++. - 
@Luis-Piña-III: once you have located the directory that @PeterJones referenced, you will see the following files:
- shortcuts.xml
 - stylers.xml
 - config.xml
 
There is also a folder named
userDefineLangsthat contains .xml files for each UDL that you have created.These are likely the files that you want to copy over; they are among the NP++ files that I have backups of on a network drive, which I mainly use for VM setups (including Linux VMs). However, as Peter alluded to, there might be other files that store other customizations that you may have forgotten about.

Thank you both!
