com.qtproject.plist
com.qtproject.plist is a macOS preference file used by software built with Qt to store app-specific settings and user choices.
What is com.qtproject.plist?
This file is a property list in your user Library Preferences folder. It is typically created by an app from qtproject or by software built with the Qt framework, and it stores settings such as window state, interface choices, recent values, or other per-user preferences. People usually encounter it when reviewing Library files, troubleshooting app settings, or removing software that uses Qt.

Safety overview
Status: Mostly safe
This is generally a non-system user preference file, so removing it is usually low risk to macOS itself. The main risk is losing saved settings for the associated app, which may reset its preferences or behavior the next time it opens.
Recommendation: Keep it if you still use the related Qt-based app or are unsure which app created it. If the app has been removed and you no longer need its saved settings, deleting this preference file is usually reasonable, but the app may recreate it if it is still installed.
