Sometimes things just go wrong.
Sometimes you can *feel* they are about to go wrong.
Sometimes you just want to take a copy of your working directory and put it somewhere for safe keeping for a little while.
Sometimes you want a little while to be longer.
When you want a little while to be longer you might like to get rid of the .svn cruft that came part and parcel with your xcopy.
To delete the .svn folders:
for /r . %I in (.svn) do @if exist "%I\." @rd "%I" /s /q
To see the .svn folders that exist:
for /r . %I in (.svn) do @if exist "%I\." @echo "%I"
