The Settings Folder on Windows
By default, PhotoLine under Windows saves its settings in the directory that the operating system has designated for it. The location of this directory depends on the operating system version, but if you enter "%appdata%/PhotoLine" in the address bar of a Windows Explorer window, you will get there.
Alternatively, you can create a "PhotoLineSettings" folder in the PhotoLine application directory. If this folder exists, PhotoLine will load and save all settings there. Please note: of course, this folder may not be write-protected.
The Settings Folder on macOS
On macOS, all settings are written to "<user folder>/Library/Preferences/PhotoLine".
You can create a "PhotoLineSettings" folder on macOS, too, in order to store all settings there. "PhotoLineSettings" must be in the same folder as the PhotoLine application. Please note here, too: this folder must not be write-proteced.
