Revert SVN repo to sparse checkout (undo 'svn up --set-depth infinity')?

Question

Is it possible to revert an SVN working copy to a sparse checkout?

I have a sparse checkout of a very large repository. I ran svn up --set-depth infinity on one of the subfolders, but this has resulted in checking out many, many files that I do not want. If I could wind back time I would do instead svn up --set-depth immediates in the subfolder, and then do that recursively only in the subfolders I care about (rather than the whole sub-tree).

I have no changes I need to keep in this sub-tree, so I'm happy to do fairly destructive things to recover it. However I do have changes in a different sub-tree, so I'd rather not just throw away the whole working copy. Is there a way (or a hack) I can just delete the sub-tree and then tell SVN to update only to depth immediates?

Answer 1

As per @Ben's comment, you can undo this by just running svn up --set-depth immediates.

Note this can take a long time if the checkout is very large!

[Updated:] After the command has finished, you then need to delete all the extra files that were checked out (--set-depth does not delete them).
