I know I can save my Gmail emails within Gmail by making a folder and archiving them BUT can I save them in their entirety elsewhere.....say in my jobs folder?
For many years I printed my work emails to PDF and saved user JOB NAMED extension.I now copy and paste to WPerf page and save with Invoice & Property Description.
This puts everything in one file.
Several ways to make this work. The simple way is to print to a pdf format file in your job folder. Then any pdf viewer will open the file. There are a number or pdf printing programs. I have used a free download Bullzip Printer for several years with good results.
More complex would be using an email client on your computer to download or synchronize the emails to your computer. Mozilla Thunderbird is the free download I use and it will allow saving a ".eml" file to the job folder on your computer. Later a number of email clients will allow printing to hard copy or through a pdf printer to create a pdf file. The web site file-extensions.org states "An eml file extension is used by variety e-mail clients, such as Outlook Express, Windows Mail, Windows Live Mail, Thunderbird etc. An eml file contains saved email message either meant as backup or for sharing."
It looks like you can save the entire set or labeled emails as mbox files.
