I think that the server will play the files in the order that they appear in the file folder when using folder view so if the filenames are in alpha order then this the order in which they will be played. I use %track% - %title% format for my filenames so this is not an issue.
On the odd occasion I've used folder/file view I've noticed that the app shows these listed in the play queue as %playqueue no% - %track% - %title% so it is listing them and playing by filename order.
I don't agree, all rips & downloads have track numbers & that controls how they are ordered in the file folder. The order they get played & if they do play in a non numeric sequence will be a function of the media server software.
I'm sorry you don't agree. By default, Windows file explorer (and I'd expect that Linux does too) certainly orders files by alpha within file folders. Of course, if the track no. appears at the start of the filename then they will be sorted in numeric/alpha order. I'm using Asset v6.1 (beta) and this includes a folder/file view in addition to the usual metadata tag based views and when using the folder/file browser view the files are served and appear in the app play queue as I have described.
The OP has indicated that the tracks appear in the correct order when choosing the "Album" (tag based) view rather than the Folder/File (non tag based) view and this is exactly the behaviour I'd expect.
