Two servers?

[Mist]

I have say one Ragnarok Online folder containing the program for a server. What if I want to play on another server but keep the old one still? Can I save the program of the new server in the same Ragnarok folder or would that mess things up?

Thanks

It would mess things up. A tip is to have a clean RO folder(I name it Gravity Fresh but that's just me.) I update the fresh folder only. Then feel free to always copy paste around for new servers.

So if you're playing 2 servers, you have 3 folders. 1 clean, 2 with privates installed to avoid errors.

makes sense... thanks a lot!

Actually i've dont it before, Just keep both DATA.INI separate and exchange one for another depending on witch server you want to log in to.

Actually this really depends on the servers you're playing. Good patchers will use little to no other files than it's own, except for the official grfs, which they don't alter. The problem is that most patchers aren't designed that well :C
So yea, you may try it and have luck, or do what Gene said.
