If you modify the list of files outside of UE then UE will not recognize it until it is forced to rescan the project folder(s) which is the case if you close and reopen the view.
I think, there is no option to let UE scan the project folders permanently in the background to automatically refresh the project tab of the file tree view. This could be very bad for performance of whole computer environment.
Maybe IDM could implement following enhancement:
- When UltraEdit gets back the focus after an other application has had the focus
- and the file tree view is currently open
- and the Project tab is selected in the file tree view
- then it should rescan the project folder(s) and update the view if necessary.
This is a feature request which you must send by email to IDM support if you want it.
I personally don't use the folder method for my projects and have rarely open the file tree view. So maybe I'm wrong with my statements above. I use the group method for my projects where I have to manually add every file to the project. I like this method more because I can control which files are part of the project and which are not. But for big projects the folder method is normally better. Using the group method means no automatical update of the project files and so I don't have the problem you have.
