Where Does PDF24 Creator Store Settings?
PDF24 Creator keeps user settings in HKCU registry keys plus file data under Local AppData folders on Windows.
Last updated
PDF24 Creator stores settings in the Windows registry rather than INI files. User choices live under the HKCU PDF24 key. Machine-wide defaults live under HKLM. File data defaults to the local PDF24 folder.
Edit through the Settings GUI when possible. The GUI writes the same registry values hand editing would. Older installs used a PDFPrint key name, so check both when migrating very old setups.
Where PDF24 stores this, by platform
HKEY_CURRENT_USER\SOFTWARE\PDF24 and %LOCALAPPDATA%\PDF24
User settings in HKCU, machine defaults in HKLM. File data defaults to Local AppData, switchable to Roaming. Edit via Settings GUI; export the HKCU key for backup.
Frequently asked questions
How do I move PDF24 settings to a new PC?
Export the HKCU PDF24 key plus the PDF24 data folder. Import the registry file and restore the folder on the new PC with the app closed. Keep machine keys separate since those belong to HKLM.
How do I switch between Local and Roaming data?
Set the roaming flag to switch data between Local and Roaming AppData. The default stays local. Change it through the documented registry value, then restart the app.
