When a file is opened with Texifier, a workspace is created for it.

A root file is a file that contains a block of LaTeX (or plain TeX) source code that is a valid candidate for typesetting into an output PDF.

This is a view containing the persistent state of the entire project for that file, including the typeset configuration, the states editor tabs are in as well as various other pieces of information that help Texifier to restore the project to its current state when you close it and reopen it.
