SVN Move in Tortoise
When you right click a versioned file it appears that there is no move function. Well there is! Read about it here.
I agree it’s non-obvious. I understand they reason why they had to do it the way they did though – my suggestion? Put a stub “Move” command in the normal context menu, with a dialog explaining where to actually find it. My first assumption was simply that Tortoise hadn’t implemented it…
