How do I delete a wrongly tagged directory in SVN?

I have a project Foo which I errantly created the wrong tag for. It should've read 'rMMDDYYYY' but I tagged it 'YYYYMMDD' instead. I realized my mistake after having commited my change. I now want to remove the YYYYMMDD folder under the tags directory and leave the rMMDDYYYY folder instead. i.e.

before: foo/ foo/trunk/ foo/branches/ foo/tags/ foo/tags/YYYYMMDD/ foo/tags/rMMDDYYYY

after: foo/ foo/trunk/ foo/branches/ foo/tags/ foo/tags/rMMDDYYYY

Any idea how I can do this please? Thanks in advance!

If you want to remove the directory then use the svn rm command:

svn rm foo/tags/YYYYMMDD

svn delete http://example.com/svn/tags/tag-to-delete -m "Tag no longer needed"

is the best approach. See also here.

Just delete the tag you dont want and create afresh with the same name or a different name. If you have tortoisesvn its as simple as deleting the directory from the repo browser. Then create a new tag.

I'm assuming you can't just delete and re-add the directory (perhaps because the working copy has changed), or you would have done that. So you have at least two options:

1. Check out the tagged revision, delete it from the repository, and re-add it in the desired location.
2. Use the svn mv command: http://svnbook.red-bean.com/en/1.0/re18.html

Note that creating a tag in subversion doesn't actually copy the files; it just creates directory entries that point to the files (See “Cheap Copies”: http://svnbook.red-bean.com/en/1.0/ch04s02.html), so you needn't worry about bloating your repository.

The Subversion Book (http://svnbook.red-bean.com) is an incredibly clear and complete reference. If you haven't read it yet, you'll probably find it to be a wealth of information.

Good luck!
