# Label locks

To tag the files that are in your client workspace and label view (if set) and untag all other files, issue the `p4 labelsync` command with no arguments. To prevent the inadvertent tagging and untagging of files, issue the `p4 label labelname` command and lock the label by setting the `Options` field of the label form to `locked`. To prevent other users from unlocking the label, set the `Owner` field. For details about P4 Server privileges, see the P4 Server Administration Documentation.
