There is no Rename Project/Workspace command within UltraEdit/UEStudio.

The name of a project/workspace is the name of the project file *.prj.

The following steps are necessary to rename a project/workspace:

1. The *.prj file must be renamed while the project/workspace is not opened in UE/UES.
2. The project name part of file name of project user interface file *.pui (workspace file) of this project/workspace must be also modified to new project name.
3. The project with previous name should be clicked in project history list in UE/UES to get this not anymore existing project removed from the project history list.
4. The newly named project/workspace is opened in UE/UES.

The project user interface file *.pui (workspace file) can be stored at 2 different locations with 3 different names depending on two settings at Advanced - Settings/Configuration - File Handling - Advanced:

1. In the same directory as the *.prj project file with file name ProjectName.ComputerName.UserName.pui with
