I am using Google code svn and have a repository setup. Inside the repository I am including TinyMCE and now I want to upgrade all the files in this folder. The problem I am having is if I checkout locally and then download their new version and replace the folder it wipes out all my svn files. So in effect removes it from version control.
I was wondering what is the best method to update those folders & files but keep the svn files intact? I have been searching but can't seem to locate any simple method.
