After my OS crashed, I've installed a fresh version (Windows 7 Pro x64).
I want to commit my project changes, so I need to restore my local repository to do this. Of course I have the all files located in my folder where was the repository before the OS crash, but of course TortoiseSVN doesn't know that there was a repository. How can I do it (I believe it is possible to restore that repository)?
If you still have your repository folder, intact with all the .svn subfolders, all you should need is installing TortoiseSVN itself after the OS reinstall. TortoiseSVN does not rely on anything outside the file system to identify working folders, so you should be able to just check in.
