Where Does CotEditor Store Themes and Settings?
Where CotEditor keeps themes, syntaxes, and prefs on Mac, and how the App Store build path differs..
Last updated
CotEditor keeps themes and syntaxes as files in Application Support, with preferences in a plist beside them. Mac App Store builds nest everything inside a Containers sandbox path while direct and Homebrew builds use the plain Library tree. Both layouts hold the same folder names.
Theme sharing guides quote both roots because installs vary. Copying files between machines works when source and target match build types. The Settings window edits the same files for anyone preferring clicks over Finder.
Where CotEditor stores this, by platform
~/Library/Containers/com.coteditor.CotEditor/Data/Library/Application Support/CotEditor/Themes
Sandboxed home for Themes, Syntaxes, and preferences plist on Store builds. Direct installs mirror the same names under plain Application Support. Match build types when migrating or folders look empty.
Frequently asked questions
how do I install a custom theme
Copy .cottheme files into the Themes folder matching your install type, or drag them into Appearance settings. Store builds use the Containers tree while direct installs use plain Application Support. The app picks new files up from either location.
how do I move custom syntaxes
Copy the Syntaxes folder to the new machine at the matching path for its install type. Preferences travel in the plist beside it. Mismatched Store versus direct paths are the usual reason a migration looks empty.
settings window or manual files
Open the app's Settings window, which edits the same files the paths hold. Manual file copies suit dotfile repos and theme sharing. Scripts live separately under Application Scripts for either build.
