Where Does SumatraPDF Store Settings?
SumatraPDF-settings.txt under LocalAppData for installs versus next to the exe for portable builds.
Last updated
SumatraPDF keeps all settings in one SumatraPDF-settings.txt file. Installed builds put it under LocalAppData SumatraPDF; portable builds keep it next to the exe.
Open it from inside the app via Settings, Advanced Settings. The minus appdata flag redirects it for shared or RDP setups.
Where SumatraPDF stores this, by platform
%LOCALAPPDATA%\SumatraPDF\SumatraPDF-settings.txt
Installed location. Portable builds use the exe folder instead, with a sumatrapdfcache sibling for thumbnails.
Frequently asked questions
How do I migrate SumatraPDF settings?
Copy SumatraPDF-settings.txt to the matching spot on the new machine. Same build flavor required (installed versus portable).
Where is the SumatraPDF history of open files?
Inside the same settings file as file states. Clearing it wipes remembered positions and tabs.
