There is no configuration setting available in UltraEdit for Windows v27.10 to automatically save all named files. This must be done manually with executing command Save all which of course results in prompting the user for the file names of all unnamed files.
However, it is possible to check the setting Discard unsaved "Edit" files with no prompt on application close after having unchecked setting Remember and reload unsaved changes to unsaved "Edit" files. Then UltraEdit prompts on exit for saving all modified files with also unchecked setting Remember and reload unsaved changes to saved files. All named files are saved and the unnamed files are discarded without any further prompts on clicking next on Yes to all or hitting either RETURN or ENTER. So it is possible now to save all named files with one hit on RETURN or ENTER and get all unnamed files discarded without a prompt on exit of UltraEdit in comparison to UltraEdit < v25.20 without the Session options.
You could request an enhancement by email to IDM support for an additional setting in Session options to save all named files automatically on exit to avoid one prompt with pressing once RETURN or ENTER or clicking once on Yes to all or just Yes on exit of UltraEdit. There would be enough space in the Session options configuration window for such an additional setting.
