Branching an existing file structure is similar to Copy Tree, but
SOLIDWORKS PDM Professional maintains the history of source files and branched files.
You can create new versions of the source files from the modified versions of branched
files regardless of whether they have been moved or renamed.
Branching functionality lets you create complete or partial copies of a
file structure with different names and place them in one or more folders. Placing the
files into multiple folders lets you edit the branched files, retaining the source files
in their original state and permission status. If the edits are approved, you can create
new versions of the source files. Otherwise, you can delete the branched files.
