I cannot find in the user guide a statement on the intended aims and so use of the project tool, and its virtues in this end, though I have made many papers and two books using versions of WinEdt. Please supply this!
The "Projects" tool in WinEdt is intended to help with the organization and management of LaTeX documents by allowing users to create and work on multiple files within a single project. It provides a workspace where related files for a project can be easily accessed and managed. This tool can be particularly useful when working on larger LaTeX documents such as books, where multiple chapters or sections are involved.
