Wow, so much easier than command line!
TortoiseSVN 1.7 has made fundamental changes to how SVN typically works where each directory contains a '.svn' file and replaced it with the 'Centralized Metadata Storage' which just has a top level '.svn' file. This is different to how the defacto standard subversion implementations all work, and removes a very useful feature. Unfortunately removing the .svn directory completely breaks how my organisation uses subversion making the new 1.7 release unfit for purpose. I understand that this is how GIT works, however subversion is not GIT and each are good for different reasons. Unfortunately the 'Centralized Metadata Storage' has made TortoiseSVN unfit for purpose in our books, and we will not be using future releases unless this is fixed. Please TortoiseSVN team if you prefer how GIT works then work on GIT, don't change the fundimental nature of how SVN works just because you thought it looked cooler. If you think GIT is cooler then please find people who still like subversion to maintain TortoiseSVN and move over to the TortoiseGIT project which needs more work on it.
