How do you remove Subversion control for a folder?
If I want to take a folder that was under Subversion and remove all links to Subversion, do I just delete the .svn folders and that's it? What else do I have to consider?
Normally yes, removing .svn folders is enough, but define "remove any link to subversion at all". Because there are such features as keyword substitution inside the versioned files.
Yes.
Though an easier way is probably to just export that folder.
I like to use deletesvn.reg. It adds a "Delete SVN Folders" to your context-menu in Explorer. Selecting it recursively deletes .svn folders, thus disconnecting your folders from SVN. The problem I've had with SVN Export, as others mentioned, is that it only exports files that are in the repo, ignoring all those hidden files you might need.
