Thanks a lot.
I did as you suggested. I selected the album “Like Minds” (Gary Burton), containing files created in november 2016. In Roon, after having setted the import date to the file creation date, here is what I obtain when I sort the albums by Date Added:
You see that the album is on the fifth screen (I have added a screenshot of the Windows file property screen, which confirms the creation date: November 10, 2016).
Then, I changed (on the Windows property screen) the content of a tag for all the files of the album, as you suggested (I simply added a commentary).
In Roon, I re-scanned the album and setted the import date to the file creation date again.
You see on the following picture that the album is now considered by Roon as the most recent one (it is now at the first place of the first screen of the album list):
You can also see that only the modification date has changed (not the creation date).
Because the import date was setted to the file creation date, the place of the album shouldn’t have changed in the album sorting screen.
Note that, if I set the import date to the File Modification date, the result is the same.
So, sorting the albums according to their Import Date setted to the File Creation Date doesn’t seem to work in my case (it is as if Roon could only sort according the the modification date…).
Unless I am doing something wrong?
