Did you know that there is no way to branch the files recursively in Microsoft VSS? Here is a work around: From Visual SourceSafe Explorer, go to View ->Search ->WildCard Search Then search for Wildcard: * (a single asterisk) with Search in current project and all subprojects selected. Then it will give you a list of ALL of your files in that project. Simply highlight them all and click on the Branch button.
