I want to use git and the recommended editor for that was notepad++.
So I downloaded it and then this came up on installation :
I don't know whether I should check it or not .
Does it makes any problems while working with git ?
This option of Notepad++ dates from the early days of Windows, when
%APPDATA% did not exist.
%APPDATA% stands for
C:\Users\<user-name>\AppData\Roaming where applications
are supposed to store their private data.
In older versions of Windows, applications stored their data in their installation
folder, but now the Windows guidelines recommend avoiding putting transient data
in the installation folder.
There is no ill-effect from checking this option, but I recommend leaving it unchecked. Whether checked or unchecked, it has no relationship at all to Git.
This option is useful to install Notepad++(along with its config data) on an USB-Stick (like the install option said) for use on several computers. So, if you put your USB-Stick with Notepad++ into another computer, the options are accessed from the USB-Stick and not from the current computer's
Repair-Sticks and similar are example use-cases for this scenario.
