Usually, the projects you want to put under version control have more than one file; it’s normal for them to contain all the files under a specific directory and subdirectory. Therefore, seeing a list of all version-controlled files beneath the current working directory is often useful. Being able to perform an operation on all of them en masse is even more useful.
