I deleted manually a directory I just added, offline, in my repository. I can\'t restore the directory.
Any attempt to do an update or a commit will fail with:
I had this error recently, when the files were excluded by settings in my SVN globals. The error was especially nasty since I also deleted the files directly from the repository - and this meant that the above solutions were refusing wouldn't work. In this case, manually deleting the .svn directory from the directory that I removed from SVN allowed me to run an update which then allowed me to commit.
