How to create an asset from c++ using file directory

i have a custom filetype I have already built drag and drop support for and I understand how to parse the file to a string and get the data out of it. in this file, however, there is one section that is a series of file directories. for example it looks something like this

C:\Textures\Texture1.png

C:\Textures\Texture2.png

I was wondering if there is a simple way to use the directory of something that the engine can import to directly create an asset in the content browser

Yes there is. Go to Editor Preferences->General-Loading&Saving->Auto Reimport. You can add Direcotries the Engine watches and also specify in which Content subfolders the asset are created.
