Library

I run Serviio on a rather large server where I have my movie database, this often causes it to crash when it gets a bit overloaded and I need to reinstall, not a major problem, occasionally just stopping and restarting the service will work.
When I do reinstall though it then refreshes the library, which takes hours! Which files can I copy out from the previous install and copy back in after so that I dont have to refresh the library? I tried copying the whole library folder but that didnt work.
help for a novice please, dont make the answer too technical (copy and paste I can manage)
Thanks!
