I recently started to getting this exception from SVN on my Windows
Commit failed (details follow):
Cannot commit 'D:\Users\Admin\AddUpdateContact.aspx.cs'
because it was moved to 'D:\Users\Admin\AddContact.cs'
which is not part of the commit; both sides of the move must be committed
Try to commit both folders together, the folder of : 'D:\Users\Admin\AddUpdateContact.aspx.cs' and the folder of 'D:\Users\Admin\AddContact.cs' and if that doesnt work:
Select the new location(AddContact.cs) when committing and add the old one (AddUpdateContact.aspx.cs) to ignore list
