I did Get All from my TFS server, and there are dozens of conflicts. I would like to keep the local versions of these files, but the only option I get is "Overwrite the local version." How do I say to keep my local copy?
TFS will try to merge the changes automatically. If he cannot do this, then he will have a conflict. Typically, you will see an option for overwriting with the server version, saving the local version, or manually merging the changes.
