I've recently added an external file to a directory that is being tracked in SVN. We're using tortoiseSVN. Typically when we add externals, we try to give it a prefix marking such that others know it's an external. However, I accidentally forgot the prefix.
When attempting to rename the file, it doesn't give me the dropdown option in TortoiseSVN like it does for other non-external files.
TLDR: How do you change the local name of an SVN external in TortoiseSVN?
