On the occasion of our member question, the process to save our emails from gmail our account locally on our computer is:
1) We visit the link https://takeout.google.com/
Select Uncheck All and select only Mail.
By default, it will save all our subfolders.
For example, if we want to save only the Inbox, then we click on
"All Mail data included" and deselect "Include all messages from Mail"
Select Inbox and click OK at the end of the list
Our final choice:
At the bottom of the page click Next Step
We have the option to schedule a periodic export of our data and select the type of compression for the file to be downloaded.
The size selection is about whether the file will be partitioned to a certain size. If the data is over 2Gb (eg 2.3Gb) then we will have a 2GB zip and a 0.3Gb.
It also gives the option of 50Gb, useful if we download data from Drive etc.
Click Create Export
and when done press Download
We are asked to verify the account (we give the password) and the zip file is downloaded.
We export the files and in the folder we will find the following

We click OK on all the notifications that it shows us and we have at our disposal offline (offline) our emails
