When I installed Thunderbird on my new computer, it immediately downloaded 3,900 emails from Yahoo (It serves my ATT.com email account.) The process took several hours and I could not stop it. My email folder on my old computer is located at: c:\emailtb1 where I have about 100 folders (I make a new folder after about 100 emails.) I tried to change my location for emails to my old location without any success. Thunderbird used to ask you for the location. Any location worked. Now, there is a complicated process re profiles, I think it is called. Why make it complicated when simple works? How can I change to c:\emailtb1 so I can view my old organized folders? My old email screen shows the 100 folders including inbox, sent, trash, etc. on the left of my screen. Then I have four columns to the right for Subject, From, Recipient and Date. Clicking on the column headings allows me to sort, and I can add columns easily. The new screen on my new computer is an absolute mess. It is many times worse than what I used since at least 2007. I have been using computers and email since 1984. I am so frustrated that I am looking for a better email program. Can anyone help? Ron Steinbach ronsteinbach2@att.net
