In Windows, the Roon folder and database are located at
C:/Users/[Name of User]/AppData/Local/Roon
The location of the Roon folder isn’t configurable. Roon will NOT work properly (possibly at all) if you move it to another location. You may end up with two conflicting databases resulting in a loss of data. I would definitely advise against trying this.
I don’t know what the database/engine is, but you might check Settings/About/Copyright Information and see if there are any recognisable database licences mentioned.
I can’t comment on the data folder location change thing, but:
It sounds to me that the problem behind your question is that you’re worried about losing the data in Roon’s database. Maybe you can address that worry by using our database backup feature? Here’s a knowledge base link for that: https://kb.roonlabs.com/Backup
(I’m glad the Sonos support is working well for you, I worked hard on it and it’s great to see that it’s useful for people.)
Sonos support is the one thing that pushed me over the edge to a lifetime subscription. I already had a significant Sonos investment and while it is de rigeur now to slam Sonos for any number of reasons, it works for me. The one place I have for critical listening I have a USB direct connection from my core to the DAC, but having music throughout the house is a killer feature.
I will for sure use the backup tools… I am a bit old school…
I also like to just ROBOCOPY C:\DATA\ROON*.* \backup01*.*
But that’s ABNORMAL and I understand… I can live with your backup tools for 13 years… at least… before I will have another thought about it.
I was just saying that’s what I would like to do but it doesn’t work that way so I will just use the built-in backup system and I’ll be totally happy because roon is so awesome.
I was just showing how an oldie in the technology world would do things but it doesn’t mean it’s the only way
