I\'ve been working on code checked out from the development line and discovered that the changes made might be breaking changes and need to be moved to an experimental branch be
Right click on the directory where are the changes you want to branch. It must not be the root of the repository, less to duplicate in that way;
Select TortoiseSVN -> "Branch/tag...";
Set To URL: "svn://host/repository/FooBar/branches/FooBarBranchName";
Make sure [*] Working copy is selected. This will ensure the changes are commited;
Log message: "Experimenting with flies :)";
Optional: Tick [*] Switch working copy to new branch/tag. This is useful if you are planning to keep working on the new branch. Although you can switch to it later too.
Try to find the OK button. Hint: it is in the lower part of the window centred.
