Try following these instructions and see if it solves your problem.

If it does not, do give a shout on where you’re stuck

My projects are currently not under any revision control.
My svn client does not have a dump function.
Or is it called export?

@Hadas, if they’re not in version control, just do a subversion checkout and then just add your files to the checkout directory.

You will need to commit your changes otherwise it won’t be saved on xp-dev.com

I created a repo called hadas and under it a project mop.
When I try to do “SVN checkout” I get the following error:
"URL 'https://svn.xp-dev.com/svn/Hadas-hadas/mop' doesn’t exist"

I am able to load the files to the repo but not under the project.
Is there something I am missing?

You’ll need to checkout https://svn.xp-dev.com/svn/Hadas-hadas first and then create a new directory called mop in the checkout directory thats on your computer. Commit that new directory called mop and you should be on your way
