I'm guessing that
TortoiseSVN is the most common Subversion client on Windows. It has a very nice point and click interface integrated into Windows Explorer.
The TeXStudio editor (which we recommend to new users) has build in
svn support, but I do not think this has been tested with
TortoiseSVN as it has a rather odd CLI interface and thus the CLI calls that TS is trying to perform to communicate with the SVN server, fails.
Has anyone any ideas as to how one can get TS to work with TortoiseSVN?
