Usually, I prefer to move all my databases to a second drive. I am setting additional folder with the same name of the FileMaker's standard folder for the databases (Databases) as always done with the previous versions.
Now when I'm trying to upload one or more files on my server using the sharing option in FileMaker Pro Advanced, I cannot see the second destination. If I create a sub-folder, this is created on the primary drive.
macOS High Sierra 10.13.4
FileMaker Server 188.8.131.52
FileMaker Pro Advanced 184.108.40.206
