Would or is it already possible to save the map files onto a different hard drive?

Describe the solution you'd like
Would like to save map files onto a seperate hard drive to save on disk I/O and space to help improve the performance of the overall minecraft server.

@TBlueF is it possible to save it on a network location?

like \\nas\folder\bluemap?

if I set that location it creates a nas folter in the server root directory.

@WoutervanderLoopNL its probably not possible then 🤔
Everything that acts like a normal folder / drive in your file-system should be possible, so a mounted drive or NFS should work ..
My guess now is that a network-location is different to that, and thus will not work..

Yes thats already possible! :)
You can change the path to where bluemap saves the files in the render.conf (the webroot config-option) .. remember to also change the webroot in the webserver.conf accordingly (they should usually point to the same directory) :)
And make sure BlueMap has read/write permissions for that new directory ^^

Consider joining the discord or r/bluemap on reddit if you need more help :)
