What is com.trolltech.plist?

com.trolltech.plist is a user preference file in ~/Library/Preferences that stores settings for software using Trolltech Qt on macOS. Qt is a cross-platform application framework used by many desktop apps, and older Mac builds can read or write shared preferences under the Trolltech name. This file typically contains app or framework settings such as interface preferences and other saved options that help Qt-based software remember user choices between launches. Users usually encounter it only when reviewing Library files during cleanup or troubleshooting. Because it is a preferences file, deleting it does not remove the related apps themselves, but it can reset saved settings for software that still uses it.

Safety overview

Status: Mostly safe

This file is a preferences plist, not an executable. On its own, it is generally low risk and does not run in the background. Removing it can reset stored settings for older Qt-based apps that use the Trolltech preference domain, so check whether you still use any Qt software before deleting it.

Recommendation: Keep this file if you still use older Qt-based applications and want to preserve their saved settings. If you no longer use software that depends on the Trolltech preference domain, you can remove it; affected apps may recreate the file later with default preferences.
