Welcome to WikiTree!
For me, a sourced profile is like a map to the information - so we can follow each other's footsteps. If you read the information in the bio of one of my profiles you should be able to find the same documents that lead me to believe it is factual, and vice versa. This is very helpful when we share the same ancestor, or maybe I have information I can share about your ancestor.
When the information leads to a file on personal computer (it looks like yours is called G: drive), then others can't see it. In this case, I would a) either upload that file as an image (and I see you're starting to do that) or b) find that same file on the internet and include the web address instead of the file name etc from the computer: (http:www.xyz.com/document.html) versus (G:/Folder/Document.pdf)
Sometimes, I might have access to a web page that you can't access, due to membership fees or copyright. Since you can't find it, and I can't copy it, I try to type out the facts that I am reading and give you the same information in the bio. To respect copyright, and save my fingers, I stick to the facts and don't type it all out verbatim.
There are different ways to present this kind of information. Some people organize it according to the source, and include the facts in that source before moving to another. (the will stated this ...; the birth certificate stated this... ; the family biography states this ... )
I'm easily confused, so I tend to write each bit of information once, in chronological order, and I have learned to use some of the formatting codes <ref>source</ref>, to create footnotes that show you which of the sources provided each bit of information. I learned how to do that by copying what I saw in the profiles that other people created.
Its a personal choice, and while we have passionate debates on G2G about style and formatting, as a general rule, as long as the information is understandable and the sources are clear, we respect the style choices of the profile manager.
