Take a look at
Why save files to a Project? I have explained there the difference between a project and a workspace.
First, it is most likely best for you to configure at
Advanced - Configuration - File Handling - Advanced
- enable Save project information for use on multiple systems
- do not enable Store project user interface (pui) files in profile directory
This is for keeping
workspace.prj (project file) and
workspace.pui (workspace file) together. Click on button
Help for details on those 2 settings.
Second, you might want to open
Advanced - Configuration - File Handling - Miscellaneous and uncheck setting
Close all files when opening or switching projects. I suppose that you want to have this setting enabled. But later after having created one or two workspaces, look on help on this setting, try the setting in both states and then take your decision.
Now with some files being opened and no workspace also opened, click in menu
Project on
New Project/Workspace. All you need to do is selecting a directory for storing
workspace.prj (project file) and
workspace.pui and entering the name of the workspace. On second dialog opened for the project settings ignore all project related options like adding files and folders, filter options, etc. and just click on button
Close.
And that's it. You have created a workspace for the currently opened files.
The project file
workspace.prj does not contain anything useful in this case, but must be kept nevertheless. The workspace file
workspace.pui contains all the data to restore the list of opened files as on last close of the workspace.
Try it out. Click on
Close Project/Workspace in menu
Project and then open any file. Click on the workspace listed now at bottom of menu
Project and currently opened file is closed (or kept according to setting). The files of the workspace are re-opened with caret position in each file restored, the active file on closing of workspace being again the active file, bookmarks restored, code folding restored, ...
BTW: If you want to quickly open a workspace in a new instance of UltraEdit without changing anything in currently running instance of UltraEdit, you can
- click on Open New Instance of UltraEdit in menu Advanced in UltraEdit and open in the new instance the workspace, and/or
- create somewhere (Windows desktop, Windows start menu) shortcuts to uedit32.exe with command line edited by appending the parameters /fni "Path to Project File of Workspace\workspace.prj"
By clicking on such a shortcut always a new instance of UltraEdit is started because of first parameter /fni with opening the workspace because of second parameter.
