Thank you for getting back to me so quickly, your explanation really helps!
So, if I'm understanding you correctly, what you're saying is that when songs are being read and edited, regardless of whether MusicBee is located on the NAS or not, they have to go through the memory system (RAM?) of the PC, not the memory system of the NAS. Is that right?
I'm not too tech-savvy and English isn't my native language, so I appreciate your patience in breaking it down for me.
Also, I think the task took longer because I was following some instructions from another thread to convert the library from ID3v2.3 to ID3v2.4, and then saving a specific tag within all tracks once I selected the ID3v2.4 option in the settings. I suppose if I were just adding a new tag without changing the ID3 system, it would be faster.
Thanks for keeping this community alive and kicking!
