Remove files from project
Select the file in the Navigation pane and choose Project > Remove from Project, or use Remove from Project in the shortcut menu of the file.
The translations of the file are removed from the project together with it. To keep them for reuse, add them to translation memory first: Add Translation To > Translation Memory in the shortcut menu of the file.
A file that belongs to an added folder cannot be removed separately. Delete it from the folder; Scan for Changes removes it from the project.
