Hello secr, and welcome to the forum.
When I try to create a new library I go to the Choose Folders window. I have my music files that I want to add in a
"Music" folder. That folder also has 2 sub-folders with music files I do *not* want to add, like this:
---Music
----Subfolder_1
----Subfolder_2
Problem is, as soon as I deselect the 2 unwanted subfolders, the Music folder gets deselected too. How do I prevent that?
This is what I observed when performing a few tests:
* The current interface does not allow you to select a folder without any of its subfolders.
* If you select only a part of the subfolders (say: Subfolder_1, but not Subfolder_2), the parent folder (here: Music) will not be scanned.
A workaround for you:
move the files present in "Music" to a supplemental subfolder, say "Subfolder_0",
and when defining the library, tick Subfolder_0, but untick Subfolder_1 and Subfolder_2.
The second question is: at the very bottom of this window there is the word "folder" followed by a text field. What does it do?
If you give a full path and hit [Enter], this will automatically select that path and all its subfolders, and display the expanded tree.
