You could use this kind of structure if you make "Source" a working copy of a folder that has 2 or 3 externals defined that pull in the desired subfolders. And there is an alternative to using externals. You can use the shallow working copy depth feature instead. Put the folders side-by-side into the repository: /trunk/Project1 /trunk/Project2 /trunk/CommomLibraries Then, either check out everything from /trunk, or check out sparse working copies as follows: svn co --depth empty URL/trunk Source cd Source svn update --set-depth infinity CommomLibraries svn update --set-depth infinity Project1 or: svn update --set-depth infinity Project2 This gives you the following working copy layout, with Project1 and Project2 being optionally excluded via depth: D:\Source\Project1 D:\Source\Project2 D:\Source\CommomLibraries If you'd like to automate depth configuration during checkout there is a helper script available at https://svn.apache.org/repos/asf/subversion/trunk/tools/client-side/svn-viewspec.py It would be nice to have this kinf of "view" feature in Subversion's core so that this would work without an external script. > I'm using Tortoise SVN 1.7.5 and this one managed to allow me to set up > svn:externals like I assumed would work.
