Home / Feature request: Purge history of opened files


With settings RememberStatePerDocument and RememberOpenedFiles activated, SumatraPDF remembers all files that were ever opened, and adds them to SumatraPDF-settings.txt.

I would love to have an option to remove those files from that list automatically that are either not existing anymore or were not used for some time (unless they have favorites maybe). For this purpose a timestamp, when each files was last loaded, could be added.

• more intuitive if a file that wasn’t used for a long time would simply start on page 1
• the settings file will grow quite large over time
• privacy reasons


I wholeheartedly agree; any program that maintains an MRU list (for anything - files, commands etc.) should have an easily accessible option to purge its history.
