2.Once you have restarted your computer create a new folder anywhere
connecting to your project like "FLDB SVN" connecting to my projects name.
3.Once you have all your work that you want to Import right click inside the
folder that you created on step 2.
4.Go to "TortoiseSVN" and click on "Import...".Put in your URL of Respitory
