Step-by-step explanation:
How to Manually Install Compare Plugin in Notepad++
Installing the Compare plugin in Notepad++ manually involves a few steps. First, download the plugin's .dll file from its official repository or source. Once downloaded, you'll need to locate the installation directory of Notepad++, which by default is C:\Program Files (x86)\Notepad++\ or C:\Program Files\Notepad++\ depending on your system architecture. In this directory, there should be a folder named plugins.
Create a new folder within the plugins directory with the exact name of the plugin, which in this case is 'Compare'. Place the downloaded .dll file inside this new folder. If Notepad++ was running during this process, restart it to allow the changes to take effect. You should then be able to use the Compare plugin by accessing it from the 'Plugins' menu in Notepad++.
Remember to download plugins from reputable sources to avoid potential security risks, and ensure that the version of the plugin is compatible with your version of Notepad++.
