这是一个很小的肮脏方式，但是(在 Windows 上)进入 AppData\Roaming\QtCreator.ini 文件和 >[ProjectExplorer] 从以下位置删除项目:

It's a littel dirty way, but go (on windows) into the AppData\Roaming\QtCreator.ini file and in [ProjectExplorer] remove the projects from:

• RecentProjects\FileNames
• RecentProjects\DisplayNames

在重新启动 QtCreator 时，只会显示您需要的项目.

On restarting QtCreator only your needed projects will displayed.

对于Linux，编辑~/.config/QtProject/QtCreator.ini
