Everything below is a direct copy and paste of the link above… but I don’t want to take the risk, should that link ever go down…

In Windows Explorer:

Right click on the folder and click Search..
Enter .svn as the filename to search for.
Click “More advanced options” and select:
- Search hidden files and folders
- Search subfolders
Press search button and delete the folders you find appropriate.

Oh, and this description is at least valid for windows xp pro.

The easiest way is by creating a .cmd script file at the root directory and execute it. Here is the code for cleanSVN.cmd :

for /f “tokens=* delims=” %%i in (’dir /s /b /a:d *svn’) do (
rd /s /q “%%i”
)

You could also just do a search in windows by pressing Ctrl + F, and then selecting find hidden files, and search “.svn” and then highlight all of them and press the delete key.
