You may also want to include *.ddp in this list if you don't use these diagrams. If you don't use Together then you could also exclude these files: *.tgs and *.tgw. For a deeper, more thorough exclude list, try the following: *.exe,*.dll,*.dof,*.dsk,*.dc?il,*.dcu,*.cfg,*.pdb,*.cfb,*.local,*.identcache,*.rsp,*.tgs,*.tgw,*.~*,*.ddp,*.bak,*.old Some may prefer to store binaries in StarTeam. If so, remove the first two extensions from the list.
