What is the Working Tree in Git?

Th Work­ing Tree in Git is a direc­to­ry (and its files and sub­di­rec­to­ries) on your file sys­tem that is asso­ci­at­ed with a repository. 

It’s full of the files you edit, where you add new files, and from which you remove unneed­ed files. Any changes to the Work­ing Tree are not­ed by the Index (see below), and show up as mod­i­fied files.

When you open the files for a project that is being man­aged as a Git repos­i­to­ry then you are access the Work­ing Tree.
