If you try to open a particular file with EmEditor — like double-clicking a file in Explorer — then, not all files will be restore but just a file you try to open.
I am not doing this.
If you run EmEditor without any files in command line, then all the saved files should be restored. This is the specification now, but I might add an option in the future.
This is what I am doing and it is not restoring the workspace.
However,I know that the workspace is being saved because if I left click on the emEditor Icon on the task basr and select restore workspace it does restore.
