I installed TortoiseSVN, when i tried to add a folder to a repository i had created with VisualSVN i kept getting the error:
"cannot be performed on a file with a user-mapped section open"
After googling around i could not find good answers to this, but I did mananged to fix the problem, heres how:
When attempting to add the folder again, I started windows process manager through task manager so that i could watch what tortoiseSVN process were running when the error occured..
I then allowed those through windows firewall and it worked fine. If you have a similar problem I hope that sorts it!
