Workspaces must be also created and of course the workspace files also have the extension .prj. In UltraEdit workspaces are projects without project files or folders. Workspaces are just for easy switching from one set of files to an other set of files. You can see the similarity of projects and workspaces in the Project menu. The menu item names are:
However, UltraEdit itself also supports remembering and reloading of last opened files without a workspace (project) file. This is like a single workspace with informations stored in uedit32.ini instead of a separate workspace (project) file.
But users who like I use multiple instances of UltraEdit at the same time don't work with the remember function of UE in the INI. For example one UE instance has one of my HTML projects open (internal company documentations). A second instance have a 'C' project open because I want to write the history about the program changes in HTML in the first project. And with a third instance I edit general text files when for example a colleague needs quick support. This third instance is opened with text file A, closed, opened with text file B, closed again, opened again with text file C, D and A. Then a fourth instance is started with files E-O and closed after a fast Replace All in all open files. And so on. Hey, I'm a power user who does nearly everything with UltraEdit/UEStudio and Total Commander. UltraCompare, WinRar, IrfanView and Opera makes the collection complete. More programs are not really needed for 99.5% of my daily work in my company and at home.
