@robeyw if your open tabs are not in those Session_timestamp and Tabs_timestamp files,, and you don’t have a backup, your open tabs are gone forever.
In 95, the “Opera Stable” folder is your profile folder. It’s called the profile folder, but it’s not literally named “profile”. The “Sessions” folder in the “Opera Stable” folder is the correct place to look and your pic shows you have the right place.
