In order to easily export files from a SVN-dump you need subversion installed and then proceed the following commands to

1. create a local <temp> repo
2. push the dump to <temp>
3. export the files (latest revision) to <folder>

So here we go:

• mkdir temp
• svnadmin create temp/
• svnadmin load temp/ < downloaded.dump
• svnserve -r temp/ -d
• svn export svn://localhost <folder>

Tested under MacOSX El Capitan

PS: do not forget to kill svnserve-daemon before repeating the above mentioned steps: ps -All | grep svnserve
