Dialog Box Items
Shows all branches of the selected file.
Projects with independent branches:
This means that there are 2 branches of this file; the first branch has moved from version 1 of the file to version 4, the second branch has the first as its parent (meaning that versions 1 through 4 of the file are the same in this branch), began its life at version 4 and was checked in once since then, moving it to version 5 currently.
